5 reasons your cat might be losing weight
1. A less than 5-star presentation
If your cat is suddenly eating less, try improving his or her dining experience. Store dry food in an airtight container to retain freshness and offer wet cat food on a clean plate at each meal. Wash dry food bowls and water bowls at least once a week. And make sure your cat’s litter is not in the same space as her food station.
2. Stress and distractions
Cats are sensitive to their environments and might react to stressful changes—like a new baby in the home—by refusing to eat. They may also eat less if they’re distracted. Try placing food bowls away from foot traffic and feed your cat during a time he or she can dine without interruption.
3. Intestinal problems
Gastrointestinal issues—food allergies, parasites or intolerance to a new food—could be the cause of your cat’s loss of appetite. Plan a visit to the vet to help rule out these issues.
Although some cats gain weight with age, others actually lose weight as they get older. This can be the result of a shift in metabolism or decreased sense of smell and appetite.
5. Diseases and disorders
If all other explanations have been explored, it's possible your cat's weight loss is a symptom of a disease, like cancer or diabetes. Your vet will work closely with you and discuss the best course of action.
If your cat quits eating altogether he may have anorexia and is at risk of developing liver disease. Again, consult your vet to help determine the cause of your pet’s weight loss and a plan for managing it.
