Cat in the hand is worth two scratches on your arm.

The last place you expect to find a cat is the first place you will see them.

One cat, two cat, three cats-how high can you count?

A cat owner is nothing but a pin cushion that bleeds.

A bad cat is told no, cats don't understand english.

Why are they named "cats"?
Because "naughty quadraped that sheds and breaks things" is too long.
