bgrnidldy,
You are lucky. Some cats will not accept any other cats in their household. My Mimi, whom I have had for 11 years, just flat refused to accept a three week old kitten into our home. We do have a "part time" cat, Thomas (at least that is our name for him), who visits about twice a day to eat his meal, but Mimi avoids him always. He is much larger than she is, but the kitten we tried to introduce a few years ago wasn't. He was a tiny baby.
The funny thing is that Mimi has accepted 4 dogs into this household at different times and trains them to respect her very quickly. But, there will be no more cats before Mimi goes to the Rainbow Bridge. She has made that very clear! I'm ok with it. Just want her to stay around a LONG time.
