Please keep your cats indoors!

Outdoor cats are bad for both the cat and the environment. Here is why:

Your cat might get hurt. Even in places without large predators, there are still cars outside, or dogs!
Your cat could get sick. Ticks and fleas are everywhere, and they might eat something gross.
Your cat will eat all the birds. Cats are really good hunters and have driven several species extinct already! Please read this Wikipedia article to learn more.
