I posted about my 16 yr old cat Blackie recently with gaining weight after starting insulin on April 26. He's always been around 10 lbs and when I took him into the vet for a bladder infection (April 16), he was 9 lbs 2 oz. Doctor noticed high glucose in urine, brought him back 10 days later to be tested for diabetes. That day he started his shots. I have noticed consistent weight gain ever since. A few days ago he was 10 lbs 14 oz. A few days ago I noticed he's been having incontinence and then noticed his stomach seems a bit large and sort of firm. He is acting as normal as can be, using the litter box and eating. The doctor is out of town tomorrow so I have an appt for Blackie Friday morning. Has anyone else experienced this?
