He's had various health problems in the last few years (tummy, teeth) and is a small, skinny boy at the best of times. His weight has been borderline worrying the last two years but this is the first time he's seemed really ill and unhappy.
He hasn't eaten properly in a couple of weeks but we thought he'd just got a bit spoiled over Christmas (he got plenty prawns, turkey etc and scoffed the lot) and was turning his nose up at big standard cat food, so we tried a couple of new types and he seemed a bit more interested, but still didn't eat a whole portion. This last few days though he's not even been tempted by poached fish or tuna (his very favourite human food) and has seemed pretty miserable. He's suddenly very very skinny, He's also swaying slightly when he stands and struggling to get up/down on his spot on the back of the sofa, and tonight he cried when he used the litter tray. He smells a bit too.
He's 18 years old, has had a long, happy, mostly healthy life and I should be ready to let him go but I'm absolutely dreading going to the vets tomorrow. He's my oldest baby. I've known him longer than DH. I feel like he's gone downhill so quickly I can't get my head round it.
