Thanks for reassuring me!

Toughcookie, all three cats are going to move to the new appartment around the same time, so there is no resident cat. They are 7 (boyfriend's cat Wissel) and 4 (my cat Piglet) years old and the kitten (Teddy) is about 10 weeks. I think the two older girls will be the biggest problem, fortunately there are enough rooms to keep them seperate if necessary.
Of course I did think this through before I decided that I wanted another kitten when we move, but there seems to be so much that can go wrong! I just hope that they will come to love eachother as much as I love them.
