I just inherited a feral neutered cat colony (previous tenant moved away from apartment complex). One of the kitties is way too friendly to have always been a stray (lets me pet him, put flea medicine on him, etc) and has a flea allergy. I've been able to apply the medicine, and hope to for months to come. Other than feed them and treat this particular little guy, is there anything I can do? I'm already waaay too attached to these little buggers that have attached themselves to me!
