my cat was diagnosed with diabetes a little over a month ago. We give him 2cc of insulin twice a day. Last week I noticed a bald spot on his spine, just above his tail. He hasn't been excessively licking or pulling it out, it looks like it fell out. Is there a possiblity that its a reaction to the insulin or is he stressed over the shots? Nothing else has changed in his environment. I've spent over $400 on him, I can't afford to keep taking him back to the vet.
It is possible that it is from stress. Keep an eye in it. If it gets worse then bring him to the vet.
