My neighbor's have an elderly cat that I don't think they pay much attention to. Blacky is obese, so at least he has plenty to eat, but his coat looks terrible. There are clumps of dirt and lose fur in his hair. I guess he is getting too old to groom himself properly (?) He comes over to meet me often when I get off from work and I pet him before going inside. Anyway, I can't take it anymore. I have got to do something about this cat's hair. I have this really great cat comb that I use to brush my elderly Siamese. She loves it. But DH forbids me to use her comb on the neighbor's cat, fearing she might catch something from him. Dumb question: Could she catch something from sharing combs even if it was washed carefully after use? I hate to spend another $15.00 on a cat comb, but one way or another, Blacky's going to have a "spa day".
