Hello! I have a 19-year-old cat (DSH) in excellent health, except that he requires Miralax and fish oil or he becomes quickly constipated. I put three drops of the fish oil in his food (wet) every morning, none in the evening; I have checked everything else, and it has to be the fish oil, he won't eat more than a few bites of breakfast but all of dinner. I want to try to flavor the oil. Is there any kind of liquid meat flavor out there I could use? Thanks!
