Sophie Stinky Toes has been an 'only cat' for about 18 months. I'm thinking about another rescue.

7. Usually grown cats despise kittens, recognizing that there's something seriously bananas about

Them. However, that's usually a short term situation. The adult pretty quickly realizes a yahoo isn't a real enemy. If you feed them fairly closely and play with a fishing rod/cat dancer toy together, that'll speed acceptance up.

You might start the newcomer off by itself in a bathroom. Sophie will smell and hear kitty. After a day, you can carry kitten out, sit near Sophie with it, let Sophie sniff it out...several times. Next, let Sophie into the bathroom with you and try out the cat toy again. Brush Sophie.

Once you're letting kitten out on its own, you'll need to frequently take it to the litter box. If kitty has a poop outside the box, pick it and kitty up and put them both in the box. If it's pee, you'll need an enzyme liquid and don't clean it with detergent.

A 3-4 month old kitten seems about right for Sophie.

It'll work out!!!
