I have my doubts. I tried to turn over a stray to the SPCA and was refused, and to give it to the pound, where it would be killed.
depends what spca or pound you are dealing with. can vary from one to the next in same region ...
many pounds claim a No Kill policy (but they sometimes have exceptions they don’t advertise, so check them out!)
here is a site with a big list of supposedly-No Kill agencies (public and private).. just pick your state...
good luck!
