OopsCat is 17, he's been doing this for about six months, not every day but a few times a week. We think he's just scratching, but it just seems very odd - he starts by just grooming, then licks more and more vigorously then does this full-body shaking thing - but he's still licking and gnawing at one spot. Then he sort of collapses and 'huffs' a deep sigh.
Is he just scratching really vigorously and wearing himself out? He's arthritic so he can't really groom very well, so we are hoping thinking it is just that he can't quite reach an itchy spot. It just seems a bit odd, especially the way he is a bit 'vacant' afterwards.
I've uploaded a video to youtube, it's .
The meowing is normal for him, he's very vocal, he was telling me not to stand in the middle of the living room pointing a camera at him!
