Why is our 11-month old cat acting weird around our new kittens?

I have chosen to share my life with a number of cats. I work with the older feral cats and the stray cats as well as bottle babies. The best tip I can offer is to work with your cat’s timetable and not yours. Before bringing the cat home make sure the cat has been to the vet, checked out 100% healthy and been spayed or neutered! Put in dimmer switches on the lights or lower wattage bulbs (night-lights work well). Make sure there is a cave-like dwelling somewhere in the room (so the cat can hide).
