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.

When selecting dry cat food diet options for this post we were on the lookout for the following nutritional benefits and diet-friendly features;

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
