Body weight has a clinically relevant effect on echocardiographic dimensions in cats, and this effect must be taken into account when determining normal prediction intervals. The association between BW and echocardiographic dimensions was best described by allometric scaling. Body weight‐based 95% prediction intervals determined in the present study may help in screening cats for heart disease.
Weight Management for Adult Cats
Obesity is a common problem in pets. A 2015 survey conducted by the estimate that 58% of cats are overweight. Of those cats that were overweight, 15% of the owners believed their pet to be of normal weight. As a guideline, if body weight is 30% or greater than the ideal weight, a cat is considered to be obese. For example, if an 8 lb cat gains 2.4 lbs (weighing 10.4 lbs) the cat now weighs 30% more than its desired body weight and is considered obese. The cause of obesity is fairly straight forward-we are feeding our cats more calories than they expend. Feeding high calorie foods, overfeeding treats, and not practicing portion control are major factors that cause weight gain. Lack of exercise also plays a role as mostly indoor cats are much more sedentary than those that spend time outdoors hunting and exploring. Spayed or neutered animals also require fewer calories per day. Lastly, changing our perception of what is a ‘normal’ weight in cats is essential for a successful weight loss program.

Why should we be so concerned about obesity in cats? Obese cats are at a higher risk for many serious illnesses: Insulin resistant (Type II) diabetes mellitus commonly occurs in cats with excess body fat. Extra weight stresses tendons, ligaments, and joints, increasing the likelihood of injury or lameness, which may eventually develop into arthritis. Cats store excess fat in their liver which predisposes them to a liver disease known as hepatic lipidosis. Obese cats often also have shorter life spans than healthy weight cats. Overweight cats may suffer from skin conditions like dry skin, or scale, which is partially due to impaired ability to groom. This excess weight also prevents adequate grooming of the hind area. A common complaint from owners of overweight cats is urine or fecal soiling due to their inability to groom appropriately. Some cats may even have difficulty using litter boxes appropriately when overweight.
