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.
Do you know any good ones?
Not really, but I probably would look up the ASPCA, which I think is a non-profit org tht protects animals. Also PETA is a great org if you're looking for that kind of stuff
I want to donate to good shelters.  Do you have dogs or cats?
I have one dog that I rescued, she's a life saver!
I adopted my dog.  She is 13 years old.
