I've got a difficult dilemma that I'm hoping more experienced whippet owners might be able to advise on. One of my cats, who is 15.5 years old, has recently started having fits occasionally. Like about once every six weeks or so. I'm worried about what might happen if I'm not around to take Gracie away from him at the moment it happens. Moses had one this evening and Gracie got quite excited and barky, as she did the previous time. Obviously the cat's behaviour when he is fitting is unusual and I'm concerned that Gracie's prey instinct might be triggered. Generally she is fine with the cats, I've got four and she has shared the house with them since she was eight weeks old. It would be so dreadful if she attacked Moses when he was fitting, and I'm wondering, if there is a real danger, if it might not be kinder to have him PTS (given his advanced years and the fact that investigations at the vets haven't shown up any treatable problems). What does anyone think? I don't think never leaving them together is going to be workable given that I'd only have to be in the garden or upstairs to not be on hand. It isn't a big enough house to keep them apart all the time.
