Gutmutter, you might like to know--as might other people- since going to a couple of cat shows , I have run into several people who say they are allergic, but the show cats don't bother them. It's because the actual allergen is the dander, not the hair. So kitties that are washed weekly or so don't bother allergic people nearly as much, for some it's not at all. And your kitty is young enough to learn to at least tolerate a montly bath, so you could wash her before your son comes. (Use baby shampoo, Dawn dish soap, or cat or people shampoo. no flea or dandruff shampoos meant for humans or dogs--those can kill a kitty or sause horrible nerve damage)
Lil Bit, that's not even funny. If I met Roxie in person, you would see how nutty I get when i see a little squishy face. But I have to admit, I do like dogs, anyd enjoy meeting and visiting my doggie friends, but am a better fit with cats.
