Combine diet with interactive play and puzzle feeders to increase calorie burn and mental stimulation.
Pro tip
Always consult your veterinarian before starting a weight loss program; they can help set a target weight and recommend a feeding schedule.
Frequently asked questions
How quickly should my cat lose weight?
A safe rate is 0.5-2% of body weight per week, depending on your cat's starting weight. Rapid loss can cause health issues.
Can I feed weight control food to all my cats?
It's not recommended for kittens, pregnant or nursing cats, or underweight adults. Each cat's needs vary.
What if my cat doesn't like the taste?
Try mixing with a small amount of wet food or warming slightly. Some formulas have stronger palatability; we've noted which ones in our reviews.
Are these foods nutritionally complete?
Yes, all our picks meet AAFCO nutrient profiles for adult maintenance. However, weight control foods are designed to be lower in calories.
Should I feed wet or dry food for weight loss?
Wet food can help with satiety and hydration, but dry food is more convenient. A combination often works well.
