He's an indoor cat now, used to be outdoors when he lived in Aberdeen. He moved to Perthshire and he never ventured further from the garden and now he's in Glasgow he hates going outside and now just stays indoor. (Family circumstances meant he had to be moved about - but he's been with me for over a year now and is all happy.)
I'd say he'd lost a little weight, nothing drastic and he was a bit chubby before.
Was at the vets a few weeks ago for his boosters and he was given a clean bill of health there.
I'm hoping he's just being a fussy git in his old age, and he'll gobble up the dried food tomorrow.
