Where does it end??

I found this cat http://www.hcaplpaws.org/cats.asp at the shelter where I adopted Merlin. She's the only one on the website that hasn't yet found a home. I feel sorry for her and keep asking my husband if we can adopt her. He tells me that we don't need another cat right now. He's not trying to be mean. He wasn't a cat person when we married, and I've already talked him into 3 cats. He loves them as much as I do, but is a bit more realistic than I. We don't have a big house. I'm still working on him, but also praying that she'll find a good home if I can't persuade him. I just feel sorry for her, because not many go looking for an adult cat. Most people want a kitten. They screen all the applicants at this place, so I know that if she was placed, it would be a good home. I
