Purring is a sign of wellbeing for the house cat. She certainly purrs because you are petting her, but if she would be sleeping on you then chances are she would probably also be purring without you touching her. Imagine this. When you pet her it's sort of like when you get a massage. You might fall asleep or you might drift off a little bit. Your cat is the ...

The main question is this: Is your dog Single coated with hairs that grow endlessly at a constant speed? Or double coated with hairs that grow to a predefined length and are shed? Single coated breeds are often "fashion" or "toy" breeds like Poodles and Shih Tzu. They actually do need regular hair cuts because their hairs don't stop ...

Cats can be temporarily paralyzed by pinching the skin on the back of their neck. This is called "pinch-induced behavioral inhibition" (PIBI) or "scruffing" or "clipnosis" (a composition of clip and hypnosis, because clips are often used in veterinary or scientific settings to keep cats immobile). It is a reflex in cats and ...

From what I understand (and a bit of time with Google), cat penises are barbed for a better grip. This makes mating painful for the female - and explains why cats mating often looks and sounds a lot like cats fighting. The other "fun" aspect of cat mating as I recall is that the female ovulates when mated, which can mean that a roaming queen's kittens could ...

Diurnal by definition means of or during the day. Animals that are diurnal are active during the day. Though times of activity of an animal are in relevance to the animal, as in it is to its advantage, it can act against it when this animal is a pet. Pets are usually diurnal, which is generally great for them since mostly humans are also diurnal, so their ...

Yes, taking an X-ray is perfectly safe, the output (radiation) is far too low to cause cancer or other dangerous changes in the body. Radiation is everywhere: the Sun, the Earth, even from natural chemicals in the body. One X-ray is usually equal to or less than the amount of radiation acquired just from living on Earth. From Harvard Health: The dose of ...

As stated here, they don't change gender. Rabbits are one of those species whose gender is difficult to tell, especially in young animals, and therefore are regularly misidentified.

There's no good reason to assume that purring is tiring for cats. Whilst the exact mechanism by which cats purr is not fully understood, it seems to be an almost passive part of breathing to them. Specifically, it seems that they have specific nerve circuitry which, when activated, causes the vocal cords to flap quickly, producing the purr we hear. As far as ...

I knew a cat who literally purred the entire time he was awake. His vet liked to say that he "didn't know how to turn his engine off". It didn't appear to tire him at all, he had just as much energy as other cats. He never had any trouble falling asleep either (the purring would just fade out over the course of a couple of minutes). I wouldn't ...

I've looked around in scientific publications and found no indication that whisker patterns are used anywhere to identify canines (neither lost dogs nor wild animals or those living in zoos). There are a few research teams and companies who are developing facial recognition algorithms for dogs, but those are all based on machine learning / AI (source 1, ...

No, snakes don't do any kind of measuring their prey before attacking like that. Typically they can see whether they can eat what they see. Similarly to how you don't have to bring out a tape measure to check whether something is bitesize. It's actually not unheard of that snakes try to eat something that's too big for them to swallow, or to mistake an ...

Cats can't literally "see in the dark", although they can see better in dim light than people can, because their pupils can expand to let more light in. So like us, they need some light, the more the better up to a point. (Glaring lights can make it as difficult to see as no light at all.) A cat's vision is different than ours in other ways. Their colour ...

The area does probably have more blood vessels than the rest of the iris of the eye, so it is nothing to worry about; it does not look inflamed or anything. I once had a cat with a birthmark on her iris; it did look like a hole in the iris (it was only a dark area). The irises of mammals are all different and can be used to identify each individual animal or ...

No thanks to our friend, our cat rapidly chased a laser light in tight circles for one minute. The result when she stopped was that she looked dazed and wobbled when trying to walk and then fell over--Classic signs of dizziness. Following a brief second she belly crawled away until she regained balance, then hid for several minutes. Though unscientific, I'd ...

It is called tapetum lucidum and it works similarly for many (nocturnal) mammals. Humans and most primates don't have it, cats and dogs do. It is a tissue in front of the retina. It lets the light go through but reflects the light coming back from the retina, sending it back to the retina and thus increasing the amount of light available for (night) vision. ...

So... First, a quick biology lesson on cones and rods. Rods are photoreceptive cells that are very light responsive and are responsible for most night vision capability. However, very dim light results in colorless vision and rods don't capture color. Cones are photoreceptive cells that are bright light responsive and are responsible for most color vision ...

Yes rabbits feel pain, I'm the anesthesiologist for our exotic pet surgeries and I can guarantee they feel pain. A part of monitoring their anesthetic depth you do a pain response by squeezing their toes, if they pull back/kick they are too light. During an ovariohysterectomy (spay) once we start tugging on those fallopian tubes and cervix their vitals can ...

Yes, all cats have retractable claws, though a Cheetah's claws are only semi-retractable. The claws on the front legs of a cat are fully retractable as they need to be sharp for holding onto prey, for climbing, or as a weapon when fighting. The claws on a cat's hind legs cannot be retracted fully, but it is less important for a cat to have sharp claws there. ...

These terms all fall under various sleep clocks that animals may follow. Sleep patterns for almost all species are monitored by the light given off the by the sun. If you've ever woken up early in the winter and noticed you get tired much earlier than you do when waking up the same time in the summer, you've experienced the sun's effects on daily life. Since ...

There are a couple of growth periods for cats. The first takes about 4 months and takes them into the kitten stage. The second growth period of a kitten takes them from about 4 months to somewhere between 8 and 12 months to adult size depending on the size of the breed. Larger breeds will take longer to reach their adult size versus smaller breeds, but ...

It could likely be a couple of things. First, it could be that they meant there are a few problem areas in the mouth, but forgot to give you specifics, using "points" as a synonym for "areas" or "issues". That seems a little strange, though, that they wouldn't tell you what the issues were. Did some brief research on rabbit teeth, though, and that brought ...

Don't panic! This is entirely normal behaviour for Gouramis (within moderation). Gouramis are part of a group of fish called 'Labyrinth Fish' (Sometimes also known as 'Anabantoids'). These fish have a special 'lung' organ called the 'Labyrinth organ' which allows the fish to absorb oxygen through the blood stream in a similar fashion to that of lungs ...

To be completely technical, no animal can see in complete darkness, although many animals see much better than us in low light levels such as the level of natural darkness that occurs at night. According to articles such as http://www.bio.miami.edu/hare/vision.html rabbits have more rod cells than humans in their eyes resulting in superior vision in ...

That sounds like made up panic. Now, I will freely admit this anecdotal, but having grown around cats, with several friends who also grew up with cats, this "ingesting cats hair is dangerous" doesn't really hold water. It is about as likely as ingesting your own hair, and about as dangerous. Now, matter is different if you have allergies, in which ...

I agree 100% with Elmy Sometimes when groomers are trained, they may not be told or may not absorb the true reason for doing certain tasks in certain ways. They may simply be told, "Don't do this". There are plenty of folk-tales circulating in the dog world that have little or no scientific basis. A groomer will know that it is a bad idea to trim ...

A cats tongue can get cut on a can. It’s not any more or less tough than your own tongue. The “toughness” you may feel is just their hairs for grooming and cleaning meat of bones. But cans aren’t bones. I don’t think it’s necessarily dangerous to let your cat lick the can. It would, however, be best to remove the lid (the sharpest part) and then feel the ...

kratzallergy.com says: If the rabbit also causes an allergy, you might consider a smaller pet. A guinea pig is a fairly safe bet for most people with allergies. If you find that a regular guinea pig causes some allergy symptoms, you might opt for a hairless guinea pig. Hairless guinea pigs actually do have hair that some people call peach fuzz. The lack of ...

If you keep the pug fit and healthy, it could likely last on a decent hike, but 15km would be pushing it. Remember that pugs are small and don't breath well. Plus, the pug will be taking, like, 10x the amount of steps you're taking, and could have difficulty navigating rocky/uneven terrain. If you walk it regularly and don't overfeed it, the farther your ...

Each hen is unique (just like people) Each hen has a number or volume of eggs that will make her start sitting. It could be anything from 1 to a dozen. Hens cannot count, there is one and more then one, and just enough If a hen wants to sit (not all hens want to be moms) and everyday you take her egg, she will try laying them in a different nest/location ...

No Unlike ants and bees, cats do not use scent as their primary sense when they move. Cat olfactory senses are quite strong, especially when we compare them with those of humans, but it will not help them move a few hundred meters. Cats sometimes have problems finding hidden treats inside the room, let alone find you from a distance. However, cats are great ...
