The complaint was a big lump in the hind leg of this 3-year-old cat that was limping. Blood test showed high blood glucose. Urine test showed glucose. The lump would be due to hind limb neuropathy which is a symptom in diabetes mellitus in cat.
On further questioning, the owner said that the cat was always looking for food, drank and peed a lot.
After insulin injections, the cat's lump disappeared and she was no longer ravenous, thirsty or urinating a lot.
