Progressive changes in weight

If your cat is gaining weight, you may want to speak to your veterinarian. Some simple blood work can determine if the weight gain is from overeating or if there is an underlying health condition that needs to be addressed.

An overactive thyroid gland can cause increased metabolism, leading to weight loss despite a good appetite.

Just like in humans, cats can develop diabetes, which can result in weight loss despite increased food consumption.

Certain types of cancer can cause weight loss in cats. Tumors may interfere with the cat's ability to eat or digest food properly.
