Hi Guys: I have 3 cats. One, is diabetic, George, and he is doing well, after an emergency visit to the Vet. this past Wed. BG was 38. , He was diagnosed on Sept. 6, 2019, w/ BG of over 600. Vet. started him on Lantus 3U. 1U seems to be doing well for George. My one other cat, female, Lucy, seems to be flipping out. She was on the sofa w/ me today, and she thought she saw something, and jumped about a foot and a half into the air. Weird behavior. Another thing she does often is take a bite or two of food, and RUNS into the basement. I never saw anything like this, and I have had a lot of cats. She is tinkling small amounts of urine in her box (I have 4 litter boxes in the basement. ) She eats ok, but looks thin to me. The diabetic cat, George, and the female, Lucy, were together when I got them at the humane league, about 10 yrs. ago. Is this crazy behavior?
