I have 5 cats total now—3 of them are foster fails. Go figure! I initially had two females (first Luna, then Panda) adopted as kittens. They were not related but eventually got along. When I fostered a first litter of kittens, Panda assumed a motherly role with the kittens, and her relationship with Luna became strained. I adopted two kittens from this foster litter (Hobbes and his sister, Patch). The 4 lived in relative harmony, although Luna and Panda were never friendly with each other again. I fostered more kittens without incident. My last foster litter, I adopted one more kitten, Emma. She’s now about 10 months old. Just a couple of weeks ago, Hobbes began acting up. He began I bully Luna out of nowhere it seemed, when they used to get along fairly well. Eventually, all 4 cats have begun bullying Luna (even then youngest, Emma) to the point where Luna refuses to leave the bedside in the corner of an office space. If I carry her out of the room, she immediately runs back. She never did this before!! I feel terrible and don’t know how to get the other cats to stop messing with her. I’ve tried feliway to no avail. Any help would be greatly appreciated.
