Except "the birds" aren't your animals. I don't know why there are so many low-quality comments tonight. It's as if people will address everything except my central point, which is: you routinely kill a bunch of stuff without batting an eye. Yet in this case, we're supposed to feel sorry for the birds, even though you don't feel sorry for flies or ants.

It's my legal right to let my animal roam. You can have a problem with it as much as you'd like. Just don't put your hands on my cat, and we're fine.

As far as I can tell, we seem to be living in an age where the entire world is a bit crazy on a certain topic. Slavery used to be legal, and normal. This to me is no different. You justify keeping them indoors for their entire lives on the basis that birds might die. That's asinine, especially from hypocrites that are happy to kill flies when it suits them. Cats don't harm you, and they don't harm your animals.
