While I think it's very important to place living animals in the right home and be careful of that, it can get so over the top and ridiculous that you drive away people that would make perfectly fine owners. Personally no one is forcing a "home visit" on me so I can adopt any animal. My privacy is my own, I invite who I want into my home and if my word isn't good enough about how I care for my animals, then I won't be adopting from that sort of person.
