Most organizations here in Phoenix will not adopt a pet out until it has been spayed/neutered. People will have good intentions when adopting, but for various reason, will not follow through. My opinion is fix them first and charge them the spay/neuter fee upon adoption. If they don't want to pay this, then they probably will not be a resonsible pet owner. Of course this is my opinion for what it's worth. If I were going to adopt a pet, I would appreciate having all this already done. Go to Alley Cat Allies website and see if they can offer you any suggestions. They're a wonderful rescue group. http://www.alleycat.org/
