because they have tails :P
for one, they are ANATOMICALLY identical. plus they have similar Biology. and cat to cat they are the same! only when you compare domestic cats to wild cats do you find differences.
some wild cats have similarities to each other, the servile and cheetah have the vary close markings but cheetahs are built to run, while servile are built to jump. the body in wild cats is much more visible breed to breed but in domestic cats to domestic cats only slight differences are in the build, like a Siamese is likely to have a thinner face and frame then say a tabby.
..the same way as all other cats, a male and a female...
No all anger is the same kind of a wierd question
Yes they can. Cat's can sense the same way a dog does and even more then a dog actually. Cats can sense pain and they also can feel other cats pain as in sympathy.
Besides there fur colour or design all cats have the same size of brain
Yes, cats from the same litter typically recognize each other through scent and visual cues, even if they have been separated for a period of time.
i really dont know why cats like each other but what ever the reason its probably the same reason we do
No, cats cannot crossbreed with other species, regardless of age. Cats can only reproduce with other cats of the same species and breed.
Because birds understand each other better because they are the same species. It's a bit like cats and dogs. They don't understand each other but cats do understand other cats.
No, they are the same as every other cat
Same thing as any other cat eats.
Jaguars play just like other cats do. If you have kittens or cats you'll know what I'm talking about. They make the same sounds and play in the same way, it is just on a bigger scale.
If there are two cats in your house, buy 2 t-shirts one for 1 of your cats and one to the other. Then rub 1 t-shirt on one cat and put it in the other cats bed to get used to the smell of the other cat.(Do the same to the other cat). This should help the cats get used to the different smells that they have on each other. (This can be done for both cats and dogs.)
