Purina OM = Overweight Management (a prescription diet for tubby pets)



In response to the original poster....

If the glucose is elevated then I can see why it is very important that your cat lose the weight. Chances for diabetes increases with excess weight.

Where I work at we've had good results with the Purina OM. Feed measured amounts at set feeding times as per your vet's reccomendations and you should see improvement at the 1 month weigh in.

Good luck.
