Pumpkin lost 2 pounds in a month

OK so here's the situation. My male cat pumpkin suffers from FLUTD as well as IBD and I know because of the IBD that he doesn't absorb nutrients the way he should. In october he went to the vet for his check up and was 9 pounds. On the 8th of this month he got his foot stuck in my recliner and I had to take him to the vet. When he was weighed he was at 7 pounds. A full blood chem and UA was done. Everything came back normal. He is hungry all the time, the problem is I am gone 6-7 hours a day five days a week.

He is on canned food only and has been eating Fancy Feast (their turkey and giblets variety). I know that leaving canned food out is not a good idea but if I want to make sure he gets the proper amount I almost have to. I am concerned about pancreatitis though I don't think he has it. I am more worried with the fact that he might have hyperthyroidism because of his constant hunger and still loosing weight. His T4 was normal.

I also wonder if I am inadvertenly causing the weight loss by not giving him enough to eat. He was eating two cans a day. I have upped it to three cans a which is why I have to leave food out for him when I leave. He gets half a can around 3:30 am then about 8 am and 10am when I leave for work. When I get home he gets food at 6:30, 8:30, 10:30 or 11 depending on his mood.

Any suggestions would be welcome.

Three cans of Fancy Feast should be plenty for a 9 lb cat to maintain his weight.  My cat has IBD but he doesn't have absorption problems.  I know that cats with this problem get routine B12 shots but beyond that I don't know anything about this problem.  Have you tried probiotics and digestive enzymes?  The digestive enzymes in particular may help because they help with breaking down food.  I have heard of people using frozen food to feed a cat while they are gone.  The idea is to feed them right before you leave and leave out the frozen food for them.  It thaws and warms up to a temperature that they will eat it while you are gone.  I really think you are giving him enough food though.

I have not tried digestive enzymes or probiotics yet. I have thought about freezing some of the food, but I am worried that he would eat the food while it is frozen. I have been adding water to his food but he doesn't seem to like it when its mushy. He gets b12 shots when I can give them to him. He has picked up the habit of running and hiding when he knows I am going to give him a shot. I am trying to find ways to help calm him to make this easier on him.
