Two of my cats had a terrible fight inside today. Both are neutered males and former stray/abondoned/homeless cats. I've worked hard to get them inside and litter box trained but they've never gotten along. One previous fight. I have Feliway spray and room atomizer and made a separate room for a stray in which I can close the doors and have tried it with one of them, Big Gray, who won't stay in it. He'd be a perfect only cat. Unfortunately, he isn't. From this site I've learned about classical music and I have that in this room along with toys, food, water, litter box, a big piece of cat furniture, etc. I hate the upset that this fight has caused and feel bad because it's upsetting my other 2 cats, who were here first. I also want this to be a nice home for all. I have another area upstairs that is pretty much the apartment of Spot, the other one involved but do I lock them up? I hate to restrain them but I can't stand this happening. If anyone can think up anything I've missed please let me know. This cat/computer room I set up for a stray from outside but have tried to use it with one of mine,Big Gray, who claws at the door until I can't stand it. Should I try to ignore it? It's not like it's a prison but maybe it is to him. I've never kept him, or anyone else, in there but should I try? Any herbs anyone knows about to calm them down? Sorry this is so long.
