So, I'm thinking about getting one or two new kittens. I have two males, and one female already, and want to get two more males. What should I expect? My three cats turned a year old last month, the two I wish to adopt are 5-6 months old. The kittens are pretty much to same size as my cats. Is it not a good idea to bring two tomcats into a home with two other tomcats that have been here all of their lives? How much is to many cats? How many cats/kittens do you guys have?
