50-new-facts-about-rabbits

Rabbits are not only fluffy animals that are massively bred in many countries. They are also surprisingly tenacious creatures that have successfully survived in the wild for many thousands of years of evolution, despite the fact that they are willingly fed by all predators that surpass them in size.

interesting-facts-about-squirrels-that-will-prove-how-special-these-animals-are

Squirrels are cute animals that many tenderly feed nuts in parks. They are widespread all over the world, and everywhere they cause only a positive reaction in people. Shy and nimble, squirrels have a good-natured disposition. True, they are not amenable to taming - caged squirrels wither away, although they live longer than in freedom.

 

Most interesting facts about squirrels

 

 

1. About three thousand nuts are enough for a squirrel to eat all winter.

 

2. The closest relatives of squirrels are chipmunks (see interesting facts about chipmunks).

 

3. Squirrels molt twice a year, but their tail hair is renewed half as often.

 

4. The squirrel's tail serves as a rudder - when jumping, it controls its flight with its help.

 

5. Sensitive vibrissae in squirrels are available not only on the ears but also on the front paws.

 

6. Squirrels live on all continents except Australia and Antarctica (see interesting facts about Antarctica).

 

 

The squirrel (Sciurus vulgaris fuscoater) is the acrobat of the animal world. She is amazed by her leaps, from one branch to another, at great heights, and by the speed with which she runs on the branches of the trees, to which she clings with her sharp claws.

 

Its bushy tail, longer than the rest of its body, makes it so easily recognizable by everyone. It is the squirrel, which the ancient Greeks called "skiouros", a name resulting from the juxtaposition of the words "skia" (meaning shadow) and "oura" (tail).

 

That is, in a translation adapted to our day, "the one who stands in the shadow of his tail." It has lived on Earth since ancient times when American zoologists discovered fossils of gray squirrels in Carolina, whose "age" was estimated to be about 50 million years old!

 

 

7. The squirrel's body does not absorb peanuts, so it is absolutely impossible to feed them to squirrels.

 

8. A squirrel can land without consequences from a height of 20-30 meters, using its tail in the manner of a parachute and thus slowing down the fall.

 

9. In addition to ordinary squirrels, there are also flying squirrels that are able to change direction in flight (see interesting facts about flying squirrels).

 

10. Squirrels often forget the places of their numerous hiding places with nuts and other supplies.

 

11. In a day, a squirrel is able to stock up on nuts from hundreds of pine cones, which it can then eat for several months.

 

12. Squirrels are excellent swimmers, but at the same time they keep their tail on the surface of the water. If suddenly the tail is wet, for example, by a wave, the squirrel will most likely drown, as the wet fluffy wool will pull it to the bottom.

 

13. In ancient times, for many peoples, squirrel skins were the equivalent of currency (see interesting facts about currencies).

 

 

We still find it in many areas of the globe, especially near wooded land, but even in parks and on the streets of villages near forests, the squirrel easily adapts to living among people.

 

And people love and protect her because she is cute, playful, and not at all aggressive.

 

Although there are no major differences between them, there are currently over 300 breeds of squirrels, divided into seven large families, the best known and most numerous being gray squirrels, flying squirrels, and tree squirrels.

 

Although rodents are not usually beloved animals, in North America a breed of squirrel has become a favorite of all.

 

This is the striped squirrel (Tamias striatus), which lives in the woods, but spends most of its time on the ground, being a bold and courageous animal that is not afraid of humans. Striped squirrels usually search for seeds and berries, but they also eat leftovers from picnics.

 

 

14. Squirrels communicate with each other using tail movements.

 

15 Squirrels are very trusting, and with a little patience, you can feed them treats from your hands.

 

16. The average squirrel eats no more than a third of its reserves during the winter.

 

17. Squirrels in captivity live longer than in nature, but they do not reproduce.

 

18. The weight of an adult squirrel, even a very well-fed one, does not exceed one and a half 

kilograms, and usually does not even reach one kilogram.

 

19. A squirrel eats an amount of food equal to its body weight in a week.

 

20. In addition to plant foods, squirrels willingly eat bird eggs and even attack young hares (see interesting facts about hares).

 

21. This animal does not breed in captivity. 

 

22. Statistics on the number of mating periods of squirrels is not true. 

 

 

Returning to the usual squirrels and their way of life, let's say that these small animals are active all year round, not entering hibernation in winter. The fact that with the onset of the cold season they do not appear again has another explanation: they retreat into holes or burrows to protect and keep their body warm, leaving their shelter only to replenish their food supplies.

 

This is also a tactic to protect against predators, which in those times diversified their menu, hunting even small animals that are not usually on the list of preferred victims. One of the few natural enemies of the squirrel remains - regardless of the season - the eagle, this bird of prey often hovering over the land on which the small fluffy mogaldetes top.

 

A curiosity that zoologists find no other explanation than that of kinship with some rodent species is that the squirrel can move through the water swimming "doggy" and using its tail as a rudder!

 

Indeed, this happens very rarely: only when the squirrel has no choice does she resort to this extremely tiring means of transportation for her. Otherwise, he runs at very high speeds or makes jumps, the length of the jump can reach almost two meters.

 

If these jumps take place at height, from one branch to another, or even between two neighboring trees, the jump can be likened to flight, from this comparison comes the name of the flying squirrels.

 

You just didn't think it flew, did you?

 

 

23. Meat squirrels are forbidden to be eaten by pregnant women in Croatia. 

 

24. Over the past 50 million years, proteins have not changed much. 

 

25. A newborn squirrel weighs no more than 50 grams. 

 

26. These animals are born without teeth. 

 

27. The four front teeth of a rodent grow continuously. 

 

28. The squirrel is considered the cleanest rodent. 

 

29. Male squirrels spend more time on their appearance compared to females. 

 

30. The smallest species of squirrel is the African pygmy squirrel.

 

 

31. About 2.5 cm long is the smallest squirrel in the world. 

 

32. In the modern world, there are about 365 types of squirrels. 

 

33. All types of squirrels are divided into seven families. 

 

34. Squirrels have a well-developed sense of smell. 

 

35. At a distance of one mile, a male squirrel can smell the female. 

 

36. Baby squirrels are completely blind at the time of birth.

 

37. At 8 weeks after birth, this rodent can see normally. 

 

38. Within two months after birth, baby squirrels are completely dependent on their mother. 

 

 

39. During the winter, these rodents usually mate. 

 

40. Winter is considered an active season for squirrels. 

 

41. The male during the entire mating season tries to attract the attention of the female to himself.

40-facts-about-cats-that-will-blow-your-mind

Do you know everything about cats? Think again. Cats are naturally mysterious, they are like an onion: endless layers! Dogs will tell you all the facts about themselves. Get cozy with your best furry buddy and learn some lesser-known facts about cats.

 

Interesting facts about cats

 

We use the term "big cats" to refer to animals such as lions, tigers, and leopards for a good reason. Cats and tigers shared a common ancestor over ten million years ago. However, today's domestic cats still share 95% of their genetic code with tigers. It's no wonder why the two exhibit many of the same behaviors, including scent marking, prey stalking and attacking.

 

1. The cat's domestication took place approximately 9500 years ago in the Middle East in the Fertile Crescent region (the conditional name for the region with increased rainfall during the winter months), where the oldest human civilizations originated developed. 

 

2. A cat's tongue is pulled out at a speed of 1 meter per second when licking liquid. Unlike dogs, a cat's tongue only touches the surface of the liquid and does not penetrate it. Then the tongue rushes up and drags a column of liquid with it. 

 

3. Currently, there are about 600 million domestic cats in the world. 

 

 

4. A distinctive feature of the structure of the cat's eye, which is characteristic of many mammals, is the presence of a nictitating membrane (third eyelid). It can be seen when the cat sleeps with its eyes open or feels tired. If the third eyelid is constantly visible, including when the cat is awake, this in most cases can be a sign of illness. 

 

5. Most cats are able to give birth to one to nine kittens in one litter. The largest known litter consisted of 19 kittens, 15 of which survived. 

 

6. The longest-lived cat ever recorded is Cream Puff, who lived 38 years and 3 days (1967-2005). 

 

7. Cats see excellently in low light conditions, however, contrary to common misconception, they cannot see in absolute darkness. 

 

8. Vibrissae (colloquially whiskers) in cats are specialized sense organs that perform a tactile function. In no case should a cat's vibrissae be removed, since by doing so it will actually be deprived of its "orientation and navigation system" in space. 

 

9. While in most countries the black cat is considered a symbol of bad luck, in the UK and Australia they are, on the contrary, regarded as animals that bring good luck. 

 

 

10. Cats have a sense of smell that is about 14 times stronger than a human's, which allows them to smell odors that humans are not even aware of. 

 

11. Mathematician Richard Montgomery once developed a special theory called the falling cat theorem. According to her, a cat falling backwards always flips upside down to land on its feet. 

 

12. A cat almost never meows to other cats, mostly this sound is intended for people. They tend to purr or hiss at other felines. 

 

13. The Burmese cat breed has a very calm, obedient and gentle character. They are very smart and sociable. As a rule, they greet guests with great curiosity and completely without fear. Unlike some other more active breeds, cats of this breed often like to sit on their laps and hands. 

 

14. Cats should not be deprived of meat food, since it is impossible to synthesize all the amino acids they need from plant foods. 

 

15. Cats eat grass, leaves and young shoots of plants to improve the functioning of the digestive system, as well as to induce vomiting to cleanse the stomach of hair. 

 

16. Cleanliness is an instinct in all felines: cleanliness of the body is necessary when hunting, so that the victim could not smell the lurking predator. They wash themselves by licking their fur at least ten times a day. 

 

 

17. Maine Coon cats are highly intelligent. This is one of the few breeds that can be trained. 

 

18. In the claws of cats there is a pulp - a blood vessel that reaches almost to the tip of the claw. In cases where the nails need to be trimmed, this must be done with extreme caution. 

 

19. Cat nail amputation is prohibited by law in Germany and Switzerland, and in many other European countries it is also prohibited under the European Companion Animal Convention. 

 

20. Valerian root extract contains actinidin, which is the culprit in the unusual behavior of domestic cats and other felines (tigers, lions, cougars, etc.). Its smell is similar to the smell of one of the components contained in cat urine. 

 

21. Cats are able to give their voice about a hundred different intonations, while dogs - only about ten. 

 

22. The Abyssinian cat is one of the oldest cat breeds. They are named after the African country of Abyssinia, now Ethiopia. 

 

23. The "purr apparatus" in cats is the thinly connected hyoid bones that lie between the base of the skull and the base of the tongue. Muscle contraction near the vocal cords causes them to vibrate. The cat makes a purring sound with its mouth and nose, and the vibration spreads throughout its body. 

 

 

24. When a cat is pleased, it extends and retracts its claws on its front paws. This movement is called the "milk step" - with this movement, the kittens stimulate the release of milk from the mother's nipples during feeding. 

 

25. Yuri Dmitrievich Kuklachev gained fame by being the first in the USSR to engage in circus work with cats. In addition to performances with cats, Yuri Kuklachev regularly conducts "Lessons of Kindness" in schools, child care facilities and even in children's colonies in different cities of Russia. 

 

26. In the UK, two cats - Humphrey (1988-2006) and Larry (2007-) were awarded the official title. Cats living in the residence of the Prime Minister of Great Britain received the title of "Chief mouser of the government residence". 

 

27. Cats are very sensitive to vibrations. They can feel an earthquake 10 or 15 minutes before a human. 

 

28. In the 1930s, two Russian biologists discovered that the color change in Siamese kittens depended on their body temperature. Siamese cats carry albino genes that are triggered at body temperatures above 36℃. In warm parts of the body, less pigment is produced than in cold parts, so the ears, paws, tail and muzzle are painted in a darker color compared to the rest of the body. 

 

 

29. Even a cat entering the water for the first time will swim well, because the position and movements of its body when swimming will be the same as when walking. 

 

30. In ancient Egypt, cats were considered the embodiment of the goddess of fertility Bast and were revered as sacred animals. The punishment for their murder was the death penalty. 

 

31. In the Catholic countries of medieval Europe, the cat was considered a companion of witches and the personification of evil spirits. Because of this, they were burned alive at the stake or thrown from the bell towers. The destruction of cats is indirectly attributed to the cause of outbreaks of plague epidemics, since there was almost no one to exterminate rats and other rodents that carry the disease. 

 

32. In Russia, a domestic cat was expensive and could serve as a valuable gift, since it guaranteed the protection of the crop from rodents. She was also a symbol of peace and prosperity in the house, protecting the house from evil spirits. 

 

33. Cats are the only animals allowed to enter the mosque. 

 

34. The most fluffy and thick fur among cats has a manul. While other cats have an average of 2,500 hairs per square centimeter, Pallas' cats have 9,000.

 

 

35. Unlike dogs, cats have not undergone significant changes during their domestication process. 

 

36. In cats, sweat glands are located only on the paw pads. 

 

37. A cat's heart beats almost twice as fast as a human's, between 110 and 140 beats per minute.

 

38. Like humans, cats have a dominant hand.

30-incredible-pictures-that-will-make-you-get-a-duck

Chickens are popular pets in the yard, but ducks have many of the same characteristics. This has led to the care of these waterfowl for feathers, meat, and eggs and simply as pets. There are a variety of duck breeds, and some make better pets than others, but they all have similar care requirements. Before purchasing a pet duck, housing, food, water, zoning restrictions, and health issues should be considered. But if you are adequately prepared for one, you will be rewarded with a few years with your feathered friend.


Cute duck pictures 


1. Flower duck


2. Lost dog


3. Strong dog


Some ducks, such as Pekin ducks, can be very friendly and calm, while others are more active and noisy. If noise is an issue, make sure you choose a breed that is not overly talkative, but otherwise sleeping, grazing, and swimming will consume most of your duck day.


Ducks, like other birds, do best in groups and will be friendlier if tamed by hand at an early age. Most ducks are not aggressive, unless they are nesting or keeping their young, so while a duck is more likely to run away than to bite if scared, this does not mean that socialization is not important. Ducks may not have teeth, but they have beaks that can hurt if bitten.


Ducks are outdoor pets, but they can still enjoy a safe home. You should have plenty of space to travel and swim during the day, but at night, in bad weather or if predators are free, you need a shelter to keep your ducks safe. A shed, a large dog house, a modified chicken coop, or a specially designed and sold duck house should be permanently accessible to your feathered birds. About four square feet of floor space is suitable for one duck, so if you have more than one duck, you may need a large henhouse or several burrows.


4. Happy duck


5. Ducklings


6. Traveling duck


Ducks do not bake, so no roosters are needed in the duck house, as they are for chickens, but they should have clean bedding to walk and stretch. Ducks produce a lot of feces, so regular cleaning is a must. Straw is best, but pine needles or wood chips can also be spread on the floor of the duck house. Wire wire grills can cause injuries, and unclean bedding can cause health problems, so the floor in your duck house is very important.


If your ducks are not outdoors in your yard or on your farm, the wire fences should be attached to the basket to keep them covered. Each duck should have at least 15 square feet of land to travel, so the space you need to secure in this enclosure will depend on how many ducks you have.


Ducks are omnivorous, so pet ducks should eat a variety of foods. A commercially available pellet duck feed should be the basis of any pet duck's diet, as it is complete and balanced, but vegetables and insects can also be offered as delicacies. Leafy greens, earthworms, worms, green peas, corn kernels and other products are healthy additives to the duck's daily meals.


In addition to the fact that there are pellets available in a feeder or in a shallow dish, fresh drinking water should also be provided. A duck waterer should be cleaned regularly and kept full, as ducks drink at least one liter of water a day.


7. Real life


8. Bath duck


9. Hello


Ducks are often considered farm animals and are not legal to keep everywhere due to zoning restrictions. Not all cities and communities allow ducks, so you'll need to check the specific rules, regulations, and ordinances you live in before buying pet ducks. Wild ducks are not legal to own, but domesticated ducks can be kept if the place where you live allows it. If pets or poultry are allowed, you may be allowed to keep ducks, but there may be specific housing requirements when they are allowed outside their home.


Since it is not legal to take a duck out of the wild, you will want to find a place where you can buy a domesticated duck. Incubators sell ducks that can be ordered online or purchased in person, but many feed stores and family farms will also sell ducks. Make sure you choose an active duck that has no eye or nose drain and has clean ventilation feathers to increase the likelihood of buying a healthy pet.


If you are interested in pet ducks and can legally own birds or animals, check out these other popular pet options:


10. Beach mood


11. Sleeping buddy


12. So cool


The rates require quite a lot of care compared to the care of chickens. They need a lot of fresh water, which they pollute frequently - so they need to be changed fairly regularly. And you'll have to do a lot of cleaning after the ducks - and it's often a lot of damp, smelly debris.


Because ducks usually cannot fly, they are a possible target when it comes to local wild predators. This does not mean that you will have to keep them closed, but when they are outside, your rates will need to be monitored and protected from potential wildlife attacks.


Rates are not doing well in colder climates. If the temperature is below -1 gr. Celsius, the rates will spend only a short time outside every day, which means more dirt to clean in the house.


Finally, pet rates can be quite noisy, especially when they want something or someone. Neighbors may not tolerate their sniffing as well as you do.


You will need a completely closed, predator-resistant shed. Ducks do not tend to fly up and perch like chickens so height is not important. What you need to keep in mind when it comes to installment payments is the floor space.


The floor matters because you will need to place a pot of water here. Ideally, the floor should be waterproof. You can use linoleum, tarpaulins or a rubber floor to prevent damage to the floor. As a bedding material you can use softwood chips, recycled paper, absorbent materials, etc.


Since the rates cannot jump, it is good that the entrance to the cottage has a low opening or a fairly wide and stable ramp for the rates to enter.


Ducks love to swim. Sprinkle with water. To drink water. To take a bath. Everything in their lives revolves around water, which means that the bigger the tub, the better.

50-interesting-facts-about-sea-urchins

Amazing creatures, sea urchins, have long tormented the minds of zoologists. These underwater animals are very interesting from a biological point of view, and the conditions in which some of their species live seem to be truly extreme. But people are willing to collect them, especially in shallow water, as sea urchins in some countries are enviable food. However, most tourists who have tried them do not share this opinion.

 

Facts about sea urchins
