Yes. In the end, thats what I thought too. They're domestic animals and if the owners are taking care of them nicely, than I guess thats not that bad.
But my first reaction was to feel sorry for them.

I know what you mean with animal abuse. I'm even a bit confused about Zoo too. But its too large to dive in. I think that there are Zoo's around the world that are awesome and animals arrent suffering.

I visited once a Zoo here in Romania. I felt terrible because the Zoo was soo small and animals had small cages. There weren't trees or grass or nothing. No friendly or natural environment.
But this Zoo I visited here its so amazing. They have big big cages. Some animals werent to be seen, that big was their space.
