Muzak is 22, DSH, extremely healthy according to the vet (wonderful bloodwork). He weighs 10.1lbs, and gets 1/2 can of friskies pate twice a day. He also (per the vet) gets fish oil and Fortiflora probiotics. His weight has stayed consistent for years, but last year or so he's been so hungry, begging two hours before each meal and eating it all within half an hour or so. Previous vet didn't have any suggestions other than pumpkin, problem is Muzak has bowel issues and should not have any more fiber than what he has now. So I'm trying to figure out a small treat that I can give him that will give him a full feeling for a couple hours. I just tried him on 1/2 tsp of mayo, he loved it and has gone straight back to his window (edit - five minutes later and he's back begging). But not sure at all that I should be giving him this. While I wait to find a new vet, what does the forum advise?
