I posted about a month or so ago about my cats but didn't get any responses. Basically one of the cats has beeb terrorising my old 20 yo cat. I've had to physically separate them as the bully cat is huge and was last physically rolling around dragging my poor old cat with him. I managed to separate them with great difficulty given the setup of our home and the fact we have other cats and dogs living here also. They were apart for about 3 weeks. Reintroduced slowly and all seemed fine for about a week but it's started again. My old boy is being stalked and pounced on when I'm not looking and I've had enough. I've tried feliway plugs, I've told him off, put him out but nothing is working. Should I rehome? This is very stressful for everyone involved.
