How do you feel about animal shelters?
They are mostly good as long as they are no-kill shelters.
I agree totally! And I think they've changed. Critics used to call anima shelters "the pound" which is generally a euphemism.
Do you know how they are usually funded?
I don't, but I do know they aren't regulated. In the US. there's no gov't run org that gives oversight at all, which is why you get the shelters that kill and hurt animals.
