Cats are like potato chips, it's hard to have only one! LOL LOL Done right, introducing a new cat with your current cat shouldn't be a problem. Since Sundance is 2 years old, introducing a kitten would probably be easy as cats seem a little more tolerant of kittens. During the transition period, be sure to lavish attention and praise on Sundance rather than the kitten, so Sundance knows that having the kitten around is a good thing! Good luck, and let us know if you welcome another fur-kid into your home!
