I'm just wondering if anyone knows why my 14 year-old cat, Jillie, might be getting a hard bloated belly after giving her an insulin shot. She also seems to sleep right after. I'm not monitoring her at home but take her into the vet about every 3 weeks for a reading. The vet and I are just waiting to see if she can handle this disease or not. She also sometimes walks like a porcupine .... her back is arched. I'm not sure if I'm doing the right thing by Jillie by making her go through this.
