We've got a new little feline (Hallie) who is about 2 and she's been with us for 5 weeks now. Our other cat (Casey) is 3. We got Hallie from a shelter where she had been for about a month - she was taken out of a hoarding situation and brought into the shelter in the middle of the night. Casey is very laid back and calm and is definitely interested in the new little one. Hallie feels a bit intimidated because she's small and is trying to find her place. We've introduced them very slowly, they each have a bedroom they can go to if they need some quiet time, we have 2 litter boxes upstairs and 2 downstairs, Casey eats in the kitchen and Hallie on the counter over the washer - they can see each other but aren't close. She started out growling at him a lot when he got too close and he just walked away. We've progressed to them both sleeping downstairs together at night and that hasn't seemed to be a problem - they each pick a spot and everyone still has body parts intact in the morning. But this last week we've gone from growling to paw fighting to coming to actual blows this morning - Casey gave her a mighty smack across the head and we think he was just fed up with her attitude. I know a lot of this is normal and them working out boundaries, but I'd be glad to know what others have done to help them get along. We've started having specific mealtimes, specific playtimes and lot's of attention. When they do start with each other we just try to distract with toys and gently moving into the area before it gets too nuts. I need to get another Feliway next week, but other than that does anyone have ideas of what more we can do or how long this might take for them to sort it out? I think we've done pretty good for only 5 weeks and Hallie has had a lot of disruption to her little life, so we're trying hard to stick to a routine. She plays like a maniac and is not keen on sharing any of those toys with Casey. We try to do play with her first, then Casey, but she'll come right after his toys as well - like having a couple of toddlers! Can anyone offer more suggestions??
