Can my Buster be cat friendly?

[JenWhite]

Hello! I am at a stand still with my pets. Buster (my Lab) is a friendly,playful overly energetic but generally good dog. I guess the energy is a bit of a breed trait Well last year we had a kitten and Buster killed him I am quite confident he was not just playing rough. My question is. . . can I socialize Buster with my new Cattens or should I just keep them separate? It is really making me anxious just walking in and out of the house for fear that one of the kittens will try to get out or one of our dogs may come into the house. Any advice or suggestions are GREATLY appreciated. TIA

Jen
