Cats and dogs do walk on their toes, in what is called digitigrade stance. This is opposed to the plantigrade stance of humans. This is shown nicely on this Wikipedia diagram, where the dog (or cat) is the middle picture, human to the left, and ungulate (hoofed animal) to the right: The cat stands on their toe bones (phalanges). Note that this diagram is a ...

This would be the Flehmen response: http://en.wikipedia.org/wiki/Flehmen_response Many animals will do this to move air over a specialized scent gland which is used to identify pheromones for reproductive and communication purposes. Our cats will do it for anything they think smells interesting, usually before they go to investigate more closely.

Rabbits make a variety of sounds. The following are the most significant. The loudest normal sound is non-vocal: foot stomps. Anyone who has seen Thumper in the Disney movie is familiar with this action. The bunny will stomp one of their powerful back legs. It conveys extreme displeasure or sends a warning of danger. I usually refer to it as bunny ...

For the most part rabbits are silent, but not entirely. We've had three pet rabbits and they did, from time to time, grunt. Most of the time it was when they got irritated by the cats, but also when they decided that they didn't like something we were doing (like stealing their plastic keys). At any rate, the grunting sound is a sign of displeasure and a ...

Cat whiskers are actually touch receptors. They have a sensory organ at the end of their whiskers that is called a propriceptor. The propriceptor actually sends signals to the cat's brain and nervous system related to the position of their body and limbs. This helps them make decisions about their next movement and allow them to gauge if they would, or ...

The fifth toe, otherwise known as the dewclaw, is set back from the main claws. It is not long enough to reach the ground to leave an imprint unless the cat travels over an extremely loose or moist surface to sink in to that depth. Highly unlikely to happen.

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, ...

Most likely these are just hair mats. They can be caused by scratching in that area, and can be aggravated if the dog's hair is getting wet when she goes outside. Once they've started, they tend to grow rapidly, so you need to take care of them or you'll end up with a short-haired dog! You can break them apart by pulling on either side of them. Do it so ...

There doesn't seem to be a huge amount of research here. I'd like to read the entire study linked in the question, but don't have access to the full text through my institution. But I was able to find an article from the Ohio State University College of Veterinary Medicine that discusses it. To be clear, the study did not investigate carrying them by the ...

All I read about colour vision of cats state: Cats have only two colour receptors (green and blue), where humans have three (green, blue and red). So, probably everything which appears red to us, may be a very pale green to a cat. On top of that, cats have much more rods in their retina than we have. This (and their reflecting sheet under their retina) ...

General Information An abnormal heart sound may affect your cat's lifespan, but from this information it's impossible to know what type of problem is causing the abnormal sound or if it can affect your cat's lifespan. You should continue to monitor your cat's breathing rate. I was instructed to measure my cat's breathing rate while he was asleep, but ...

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. ...

I'm not sure about what passive noises they make, but I do know when rabbits are really stressed/scared, they make a human-like screaming noise. They make the same noise to a lesser extent when fighting. It's more like a chirping/squealing noise if I remember correctly. It's been a while since I've heard rabbits fighting.

Continuously (if slowly) shed and replaced; nothing to worry about. I'm always amused by finding a whisker; I forget just how long they are compared to the cat until I have one without the cat attached, and I find it interesting to ponder how that would scale up if large cat's whiskers were the same relative length.

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 ...

A chicken's beak will grow back over time. Presumably, the beak was trimmed by someone who knew what they were doing. Any attempts on your part to correct by trimming the lower part are likely to just cause more issues. As a now free range chicken, they should both manage their own beak growth; they may choose to rub the bottom beak against a rock and ...

I think a cat's personality is too subtle a thing to be rigidly controlled the few genes that the theories ascribe. Orange color, and Tortie color is controlled by a single sex linked gene. This supposedly makes friendly Orange males AND stubborn Torties. White cats are often made by a second single gene, and these cats can also have the same gene as an ...

Whiskers on a cat serves several functions, as noted below: The whiskers will detect even the slightest changes in air currents. This is tremendously important when moving around in the dark. The air pressure changes as it hits any solid forms such as furniture, walls and so on. The cat whiskers inform the cat of all possible obstacles. This is why the cat ...

They're called "vibrissae"-- they're not defects, they serve an important function. They're sensitive receptors, like a cat's whiskers. They pick up air currents and alert a dog to any movement or change in their immediate surroundings.

Color of whiskers isn't set in stone, nor is their transition. Some cats start black, other cats start white (one of our current cats has black whiskers at age 1, the others have white whiskers at age 1). I've had a cat who kept white whiskers to the day she died (age 21). There's likely no guaranteed answer here, only an average approximation.

According to Jacob Markow, a supposed "zookeeper who specializes in the care of tigers and other big cats", and an "animal handler and trainer", who answered the Quora question: What does it feel like to touch a male lion? The male's mane is, as you might expect, a bit tangled in general. These guys rarely get a spa day and thus their ...

No, don't worry. Those "bumps" are completely normal. All dogs got them, it just depends a bit on the race how well you can see them. They're very noticeable on our Husky for example. As you've noticed and others mentioned, they are the areas where the whiskers originate. Just check those three spots occasionally, as there might sit ticks right next to ...

I happen to have a cat skeleton model nearby (and two now-very-annoyed cats). The tibia/fibula of a cat (another pic, items 13 and 16) have separation, much like humans. The difference is the muscle distribution. Here is a pic (and another) showing the rabbit/chicken-like muscle shape of the rear leg. The rear leg of cats is hard to describe since the ...

Yes definitely pregnant. As Dalton says, you may want a birthing chamber to put her into. From experience I would also look into sexing guppies if you want to keep your tank population in check. Guppies breed like rabbits. You can generally sex the fry (baby fish) at around 3 weeks. I didn't learn this process quick enough when I was a teenager and went ...

LFlare is right. You have a pregnant female guppy there. It's a fuzzy pic, but it looks like she's got a while before she pops. What you need to look into now are live birthing chambers to keep her from eating the babies and deciding whether you'll let them into the main tank to take their chances or put them into a separate baby tank for a few months. I've ...

Sounds like a heart murmur. There are different types of murmurs, so there's no way to say in general how it will affect your cat. Our cat has one, and when we asked the vet the question you're asking (if it will affect lifespan), he said there's no way of knowing. He said to have it checked periodically to have it checked for changes, or bring him back if ...

In my experience, cats shed the same amount of fur after they are spayed/neutered. I have had cats that have been unneutered and unspayed and I have not seen any difference in the amount of shedding after they have been spayed/neutered. Not even when the cats have been exposed to the stress of getting a new home where another cat was living. Cats do normally ...

The „pimple“ is a normal part of the bird’s anatomy, it’s the uropygial or oil gland and it produces the oils necessary to waterproof and care for his plumage - think of it as nature’s conditioner. Usually the gland is barely noticeable, because it’s hidden in the feathers. I am no vet, so I can’t judge whether the appearance is as it should be (it differs a ...

Not sure how many bones are past them, but those toe-beans look like they're exactly where I develop callouses on my hands. So they're kinda walking on their palms. (Reddit) (tinkercad.com) Put your fingers flat on a table and lift your palm. And then imagine that you can still do things with your nails.
