You're right, it is disgusting Bettababe. Over the years I've found that were there is money to be made, there is some slimeball who will do it.
These kind of people don't care about the animals involved. They are just a commodity to be bought and sold. The people doing don't even care if the animals have feelings. It just doesn't matter to them. Only the green does.
Unfortunately it encourages people to treat these animals as just things to be had, not as animals with feelings. They just consider it another decoration and will probably just flush the lot if they actually become work.
It's a horrible truth, but it's the reality of the situation. All we can try to do is convince people that it is bad to treat animals in this way. Even if you save just one, you've done some good.
I'm rather rabid in that respect myself. If I think an animal is being mistreated or abused, I'll say, or do, something about it.
