Already have a kitten, and a cat.
The cat is 20lbs, and has paws big enough to slap small children around. The kitten is 4lbs. The kitten is the dominant one of the two. You figure it out.
Fortunately, a good front-declawing has put an end to Indiana-Jones style climbing of the drapes. However, chewing is still a problem. Someday, I envision the wife telling a student of hers in class, "I'm sorry, the cat ate your homework".
