Hi! I have a 14 yo controlled diabetic cat on Lantus (1U 2x day). This site & these forums have been extremely helpful but I’m not seeing anything regarding this. My cat is losing muscle mass - quite significantly. He’s been diabetic since 2017 & controlled for the most part with Lantus. I had some issues with controlling his diabetes at the end of December- early January likely due to stress (we just had a baby, I home test or I wouldn’t know this as he acted normal) but seems to be controlled now. I took him to the Vet and they believe the reason for the muscle loss is lack of enough protein. The Vet went on to state that cat food labels are really not very reliable & that high crude protein doesn’t necessarily mean a high level of digestible protein (what they need). They rec. Purina DM. I have been feeding him Tiki Chicken, Tiki chicken & eggs, sometimes Wellness pate chicken & Caru chicken/turkey. Has anyone encountered this before?
