Remission - food + underweight?

[Riulake]

Hey all! It's been a while... which is a good thing, right?!?
My guy has been in remission since mid-August 2018, pretty stable but with some bumps in the road likely due to either mild pancreatitis or IBS.
My question is, I've still got him on nothing but LC Friskies Pates and he's super super tiny. Like the vet said possibly underweight. Is there anything safe I can give him to bring his weight up? Perhaps a still LC but higher fat?
NOTE: Already at 4 meals a day, would be really difficult to squeeze in a fifth.
NOTE: Already using automatic feeders for during work hours.
NOTE: He still thinks wet food is a treat and gorges and vomits. Can't really increase the portion size.

Has anyone been in this situation?

Thanks in advance!

Why not just feed more of current diet?

We’ve tried, but he’s a small guy in general and if the portions are any larger he’ll gorge and vomit. And we’re already at four meals a day... I honestly don’t know where we’d squeeze a fifth with work schedules .

Could you add a protein source like cooked chicken?

Could you try an auto-feeder for when you are not home? Or maybe look into kitten food? I'm not sure about Friskies but I believe the Fancy Feast kitten pates are low carb and higher cal.

@majandra Interesting idea... he is tolerant of chicken. Maybe that’s something to try, thanks!

@SpotsMom We do use auto-feeders for his morning and lunch feeds and they’re super helpful! I am intrigued about this idea of kitten food... I might pick up a few to pepper into his normal meals. Thank you!
