I have 3 cats (well kittens) aged 7 months old, 5 months old and 4 months old. The oldest is fixed, and the others will be as soon as they are 6 months. They get along great, and I would love to introduce another kitten when we get a new place in 2 months. The thing is, my OH wants to wait until next year. They are so young and playful now, would it be a better idea to get another kitty now, so they get through the kitty months together, or does it make much difference introducing a kitty when they are all over a year and a half? Any advice is much appreciated! Also!! Has anyone ever introduced a puppy to fully grown cats? As in more than 1 cat (or 3 to be exact! possibly 4:wink5 as I want to get a dog in the next 2 years!!! Thanks!! ps I know I'm crazy! I just want to share my home with rescued animals!
