I also would prefer they leave it out. Maybe it breaks down differently than the beef when freeze dried????
As to effecting their overall health..... so far so good. I have had full labs done on Hidey 3 times since his diabetes diagnosis because my vet was thinking he was showing beginning kidney issues. Since I changed his diet to fit his diabetes, all his labs have turned around for the better. When he was diagnosed he was getting Halo a LOT, more than I should of but I felt guilty with all the testing and shots lol. Since remission he gets about 4 pieces at night (nickel size I guess). Its become routine lol. At 10 my one cat (Hot Rod) starts crying like crazy for his chicken lol. They have never looked or acted better! Im trying to get my parents to switch their cats to Halo as well, instead of temptations.....but some people are stuck in their ways lol
