Aggression in Senior Cat
I have a 16-17 year old cat and she has always been VERY affectionate and social, but recently she has started to become aggressive and attack me. It's happened a couple of times now. The attacks are totally unprovoked and not a result of like over-petting or excitement or playing or something clear-cut. They have all occurred on the bed though, so perhaps it's a territory thing. One second she's sitting next to me, or looking at me, I am not touching her at all, and then BAM she grabs my arm or hand and scratches and bites it. I typically try and do nothing so as to avoid threatening her and prolonging the attack. I don't scold or react at all. My hand has become infected once already though and required an urgent care visit.
Does anyone have any advice? I have read that this can happen with senior cats but that it usually happens for some underlying reason? I took her to the vet but no tests revealed any issues. They recommended meds to treat arthritis just to see if it helps.
Does anyone have any experience or advice?
I think I am going to have to start locking her in another room overnight to ensure I don't get attacked while I am sleeping, but this will surely cause some distress to this elderly animal and that could make things even worse. I'm not sure what to do.
