You can't see it and no matter what anyone here says, you never will.

God help these poor confused animals.

I hope you find the love (or whatever it is) that you're looking for and stop this. The worst part is that you're doing a horrible thing not only to the animals, but you're teaching your kids a horrible lesson: If it doesn't work out, don't put forth the effort to make it work, replace it with one that might. Not a good lesson to teach, and you're teaching it again and again and again.

I'm done. You don't even want to understand or see it.
