Carole,

Keep him. He's only 4 months old and I think that in time Lexie will come around. Is Lexie an outdoor cat??? I don't think she'll take off from her food source just because of the little guy.

Your daughter sounds like every parent's dream (Just like my daughter Amy) . How about typing up a contract setting down everything you guys agreed upon with respect to the kitten. This way, just in case, although I'm sure there won't be any problems, you'll have something to refer to. This also might help in convincing Dad that it's going to work out.

He sounds like a keeper to me, Carole. Go with your gut instincts.
