Weight loss coupled with a normal or increased appetite can be a sign of diabetes or hyperthyroidism, to name a couple of possibilities. I recommend getting Felix seen by your vet as soon as possible for an exam and labwork to determine the reason for his weight loss and get him started on treatment.

Weight loss in cats is due to either: 1) Intestinal parasites, 2) Hyperthyroidism, 3) Lymphoma- which also causes vomiting and often-times loose stools in a pet that is eating well. You will need to get Stallone seen by your vet for testing to determine which is more likely so that you know exactly what Stallone needs to treat his condition and get him well. In the meantime continue to feed him as normal and monitor his stools (if possible).

Skeeter needs to go see his veterinarian with in the next few days. Rapid weight loss is always concerning. Older cats can develop a variety of conditions which will cause them to lose weight including diabetes, kidney disease, hyperthyroidism or cancer. Less common causes are also possible. The doctor will need to run some blood samples and a urine sample. Be sure to bring in a fresh stool sample in case the doctor wants to check for parasites. Don’t wait as all of these conditions have a better prognosis if treated early. Best of luck.
