Is your kitty overweight? If so, you’re not alone. Studies have shown that as many as 63% of cats are either overweight or obese (20% or more than optimal weight). Feline obesity is associated with an increased risk for a number of diseases, including diabetes mellitus, osteoarthritis, heart disease, hypertension, and urinary tract disorders. Clearly, achieving and maintaining an optimal weight is an important goal in helping cats live healthier lives, but knowing how much to feed and keeping your kitty on track with their weight loss program can be challenging.

To help address this significant problem in feline health, the Cornell Feline Health Center is proud to offer Purrfect Weight™, an innovative iPhone app that helps owners achieve weight loss goals specific to their cats. Using one of the proprietary cat foods in our extensive database or other commercial foods that you can add at your choosing, Purrfect Weight™ calculates an individual weight loss plan for your otherwise healthy overweight cat based upon their weight and body condition (determined by a veterinarian). With schedulable reminders to feed and weigh your cat, feeding and weight tracking features, helpful tips for achieving a healthy weight, and prompts to visit a veterinarian if your cat loses too much or too little weight, Purrfect Weight™ is an easy-to-use tool to help you help your cat achieve an optimal weight and improved health.

We look forward to supporting you along the path to improved health for your cat. On behalf of all of us here at the Cornell Feline Health Center, thank you for sharing our goal of a better world for all of our feline friends.

I’m giving it the benefit of the doubt because the concept is good but it needs work. When you add a wet food you are asked for the calories per ounce and the weight of the can. This should be the number of calories in the entire can; information supplied on the can label. The can sizes offered are only 3, 5, 5.5 and 6 ounces, not flexible enough. I had a can weighing 5.8 ounces. Once you enter a food, it can’t be edited, you can only delete it and re-enter it. Right now, the database of cat foods is limited, meaning all the foods I feed my cat had to be entered from scratch. If the database is expanded, this would save a lot of time. I look forward to seeing improvements - my cat needs to lose 2 pounds.
