Yes I think he needs to increase his dose.
So even when he had his initial bad pancreatitis he still ate, but less than normal. He also sat near food in the quesy kitty loaf position. He didn't throw up, he did have a major fever. He generally was weak and sad and was completely glued to me.
Since then he's had what I think are a few low level bouts of pancreatitis. Because he still eats and drinks I mostly just let him do what he wants and gave him doses of metacam for a few days. I've not given him metacam since his diabetes diagnosis because I'm not sure he can have it. I'm seeing the vet on friday so I can ask then.
How he was this last few days- subdued, still eating, stomach slightly potbellied, didn't see him sit in quesy kitty loaf position, felt warm not feverish (but this has been a symptom for months and heat intolerance was really what made me initially think he was ill)- so something probably has bunged him up and this wasn't pancreatitis in this case. Although he is still feeling fairly warm, again not to the point of fever.
I'm going to speak to the vet about his temperature again on friday. As the weather cools down and he is still having to seek out the cool kitchen floor it's becoming more and more odd. Whether he has chronic pancreatitis that's presenting oddly, an infection nestled somewhere causing mildly raised temperature, his diabetes is actually caused by agro and that's raising his temp ( seems to do that is some humans, haven't read it as a symptom in cats?), hyperthyroid- doesn't have any other symptoms or something else it just doesn't seem right.
I think I'm going to ask for a longer course of antibiotics for a start and then maybe blood tests after that. Also will ask about painkillers although now I'm monitoring his food so strictly I'm hoping there won't be any more pancreatitis
