Cats usually walk alone.

Cap, I saw a documentary on cats about a year ago that said that, when left to their own devices, female cats live in groups (like lions) and it's the male cats that roam solitary. Aparently, it is to protect the kittens since male cats will kill off any kitten so that they can mate with the female an produce their own offspring.

The female cats protected the kittens whether they were their's or not.

The documentary also mentioned something about cat killing loads of birds and mice in a year. I don't remember the exact figure. What they did is, they went to a village and asked all the cat owners to count all the birds and mice that their cats brought home in a year. I remember that the numbers were staggering. I wish I remembered the exact amount.

What I found the most surprising though was that, apparently, it is only cats that are raised around humans that meow. They also found that the cats had many different sounds to communicate different things to their humans. Whereas in the wild, their vocal range is limited.
