According to the Association for Pet Obesity Prevention, in 2018, an estimated 60% of cats in the United States were overweight or obese. This is a serious problem as feline obesity predisposes cats to a number of devastating health complications, including (but not limited to) insulin resistance, diabetes mellitus, lower urinary tract disease, osteoarthritis, and skin problems.

Weight loss tips for cats:
In addition to switching your cat to a high-quality weight-loss diet, you can also try the following;
- Add water to your cat’s dry food, as research suggests that this helps to promote physical activity (it’s also beneficial for urinary health)
- Ditch the gravity feeder to prevent overeating (portion control is crucial)
- Monitor your cat’s daily food intake to avoid excess calorie consumption
- Limit treats and be sure to include them in your cat’s daily calorie quota
- Consider multiple (more frequent), smaller, portion-controlled feeds per day to reduce the risk of potential problem behavior resulting from a restrictive diet (research suggests that this may help to decrease hunger and frustration while promoting spontaneous physical activity, water intake, and urine production)
- Use puzzle feeders and environmental enrichment for added mental and physical exercise (especially for indoor cats)
- Weigh your cat and evaluate their body condition score regularly to make sure you’re on the right track
- Consult your vet if your cat is still having trouble losing weight
