I've got a question.

I have a question about the cats in my yard.

God forbid a cat I feed (or any outside cat in general) got hurt bad and was laying in my yard badly injured, and I cant afford to pay for it be humanely euthanized due to having no job, what do I do, who do I call for help?

You could call animal control or take the kitty yourself to a Humane Society.

Yes, generally they will euthanize a badly hurt cat that you bring in. Tell them it is a stray.

Ok I contacted my local shelter and asked if I found a badly injured stray what I should do.

They said If a cat is in such condition that it needs to be Euthanized for humane reasons, then an Animal Control Officer will pick up the cat. There are no veterinary services for cats.
