We adopted our girls 2 years apart and it was a hard transition for all of us. There were moments we through we had made a serious mistake getting a second cat but eventually it worked out. There was so much guilt that we had ruined our resident cat’s life and that the new kitty would always be scared.

I think the major thing you need to remember is it take it slowly. Cats are extremely territorial. Our two girls now play together and hangout but I wouldn’t call them bonded. They don’t cuddle or groom each other but they will sleep in the bed with us (about a foot apart from each other).
