New to the group here. I adopted a male diabetic cat about a year or so ago. They thought he was about 12 y.o. at the time. He was doing well on a lot carb wet food until I noticed him losing weight. Discovered he was only licking the gravy off the food and leaving the rest. Switched food brand to a pate and he did better. Then came down with a UTI. Was put on a urinary health diet by the vet but it isn't lo carb. He quit eating that too so I went back to the previous food. He eats but is still losing weight. He's been getting 3u lantus every 12 hours. Any suggestions would be appreciated.
