Over the last 2 days my cat seems to be a bit off-colour. He's very quiet and subdued. He has been eating - but only a tiny bit. He's not finishing his meals. He just generally doesn't seem to have his usual enthusiasm. I'm worried - he's diabetic and has to have insulin twice daily.
Hello, my name is***** and I have over 20 years of experience as a veterinarian. I'd like to help with your concerns about Bob's lethargy and decreased appetite. I think you are right to be concerned.

Because he is diabetic secondary infections, gum and tooth root infections, as well as urinary tract infections are more common and they would both explain the symptoms that you are noticing.

Diabetic cats are also more likely to have secondary organ failure, especially kidney failure because the kidneys process excess glucose and fluids in diabetic cats, and are more likely to develop pancreatitis, which is an inflammation of the pancreas leading to increased enzyme production and release which can cause abdominal pain and nausea.

I am sure that your veterinarian has told you not to give insulin if he ever doesn't eat. Giving insulin to a kitty that hasn't eaten can cause dangerously low levels of blood sugar.

For now we can try giving him and acid reducing medication to see if that makes him feel better and improves his appetite.
At home you can give either:
1)Pepcid ac (famotidine) at ¼ of a 10mg tablet per 2 to 4 kilograms of body weight every 12 hours
2)Prilosec (omeprazole) at ¼ of a 10mg tablet per 2 to 4 kilograms of body weight every 24 hours
These acid reducers may help him feel better. They are quite safe and can be used as needed.

You can also add warmed, low salt chicken broth to tempt him to eat a bit better (as long as there isn't any added sugar).

Then I do recommend that your fellow see his veterinarian on Monday to look into the changes that you have noticed with him.
If he stops eating, starts vomiting, has a tense painful abdomen or runs a fever then he should be seen on an emergency basis.

Please let me know if you have any further questions.
