Our latest fur baby (Roo Ella) who joined us in June of this year at age 7 is a big cat! She gained weight since joining us and now weights 15lbs 15 oz. We want to continue her on a wet food diet to lose weight to decrease her risk of becoming diabetic. We have been feeding her Friskies pates in an amount for a 12 pound cat using the guidelines on the can. However, she gained over two pounds. Does anyone have any recommendations for weight management food? Thanking you.
