He came out of hospital and was fairly chipper - but not as confident as he was. Within a week the fever had returned so I took him back to the vet. He was given an injection for his temperature and we came home with tramadol as a pain killer and antibiotics. This was yesterday. He sat in his room all day yesterday (he has 'night room' because our ex-feral male won't come in the house unless he's in a room. Such has been the charisma of Charlie). Today, he has sat on the desk in the room next to his food all day. All he wants is food, but he's only grazing a little on the Purina hypoallergenic biscuit and licking the gravy off the Royal Canin Sensitive Low Calorie wet food. He wants it - it's just not exciting. For Charlie food is the most important thing, other than following Mummy around and being loved. He didn't leave the room all day, and hasn't since Wednesday, to be honest, when he started looking unwell again. He simply won't come out of his room. To some extend this is not new, as he's been reluctant to come out since he's not been well, but now he's quite sure he's not. I brought him downstairs yesterday and put him on the sofa, which he normally loves (next to me) and he ran back up to his room.
This morning I got his antibiotic pill out to crush it and hide in his food, and he crunched it down hungrily as if it was a potential treat. I feel so sorry fr him. He won't come on the bed with me, and he won't come downstairs. He seems to have lost his mojo almost completely.
I've no experience with pancreatitis or managing long time dietary exclusions - Charlie likes varied Felix AGAIL diet but the vet says this is now too rich for him. I have to feed him I type/actual food only, or two at the most. I've gone for 1 wet + 1 dry because he normally likes wet but sees dry as treats - so doesn't live on it. I want to do the right thing for him but I'm concerned that he's not himself. He feels warm to me, but he has a shaved tummy so maybe I'm just not used to bare cat. He's certainly but not listless like he was with the temperature. He's very purrry and loving on his 'surface' if he thinks I'm going to feed him. But the way he's just sitting up there all day makes him look a bit zombified or that he just can't be bothered. He's just going to wait next to the potential food.

Does anyone on here have experience of cats recovery from pancreatitis? I have one cat-lady friend but her girl was almost straight away back to her old self when she came back from hospital - certainly not afraid to come out of her room. Anyone have experience of a cat on tramadol? Can this sort of episode along cause a character change or is he still likely to be in pain? Am I worrying too much and he just needs time to settle down, or should I be concerned?
If only cats could talk human language...
