I think you did the right thing. A friend of mine let a roomate move in with a cat, after asking everyone else in the house if it was ok. One response was "well ok but I'm allergic and I don't like cats, but.. ok" Well, that guy tortured the cat (sprayed her with water ALL the time, kicked her out of his way, hissed at her when he knew it tormented her), to the point that she was terrified of him and was exhibiting anti-social behaviour. They ended up having to tell the cat hater to knock it off or move out (he did say ok, afterall) and he ended up leaving the house. They have since moved and no longer have roomates and the cat is doing great, but it was tense for a while there. At least my friend chose the cat over the stupid cat hater!!
