A few years back I trapped a feral cat on the back porch that was hanging around kickin the other cats butts. We had taken several cats in that we fed and they made good pets. All our cats roam in and out of the house.
I took the captured feral cat to the shelter. While there, and telling them I had caught a feral cat, they were befuddled to hear I wanted to pay for the cats adoption fee. They asked "I thought you said it was not your cat"...and I said it was not. I'm sure they thought I was lying. However, I stated I did not catch the cat to simply bring it into the shelter to then have them kill it. I wanted to pay for the adoption so money would be no object in getting it a nice home.
They said they were not sure if they could do that. I said "Your telling me you won't take my money?" They were baffled. After several phone calls to the director and other folks, a half hour later they said they in fact would take my check. But no assurances could be given that the cat would be adoptable. I said I could live with that.
Two weeks later, I was informed that the cat was put down. That the money was in turn used to discount two other cats so other families could adopt their cats at a discount. The shelter even included two pictures of the families with their pets. I can honestly say, while I do have some problems will "kill" shelters, I admire the workers and those folks volunteering their time and services.
While I am a hunter, meat eater, and give great latitude in allowing folks to keep animals as they see fit....I completely detest folks who abuse animals. I think animal cruelty is one of the lowest form of ignorance one can have.
