Unfortunately Axel is our reason for not having more permanent cats. He and our one other cat, Murphy, have been living together with us for 5 years and they still fight like crazy. Axel *hates* other cats (obviously this was something we did not know before we adopted our second cat!). Any time he's so much as caught a glimpse of a foster, he starts growling. Grouchy dude! But I guess it's a good mechanism for self-control...I imagine we'd have a lot more cats otherwise.Has Axel met your mama kitty? I know it's too early for him to have met the kittens. Is he curious about them?
