Keeping Your Maine Coon at a Healthy Weight
-
Feed the right amount
Adult Maine Coons need 220–380 kcal/day. Use our food calculator to dial in exact portions.
-
Meet daily activity needs
Maine Coons need about 30 minutes of activity per day. Regular movement is the most effective weight management tool.
-
Limit treats
Treats should make up no more than 10% of daily calories. Use kibble or low-calorie treats for training.
-
Weigh monthly
Weigh your cat at least once a month on the same scale. Early weight gain is much easier to address than established obesity.
-
Annual vet check-ups
Your vet can spot weight changes you might miss and check for underlying conditions that cause weight gain.
