Several conditions that tend to afflict older cats can cause them to lose weight, including kidney disease, cancer, diabetes, dental disease, hyperthyroidism and arthritis. Your first step should be to identify and treat your pet’s primary condition. For example, if your vet pulls painful teeth, your cat may start eating again naturally.
Work with your vet to identify the best high calorie cat food for your senior cat. Some of the best high protein cat foods are actually formulated for kittens. Take a look at all Petco’s high protein cat food.
You may also want to ask your vet about adding probiotics to your dog’s diet. Slow feeder bowls may also help—they force your pup to slow down when eating, which can help reduce bloating and excess gas. Slow feeders may also help prevent Gastric Dilatation-Volvulus—also known as GDV—which can be deadly to your dog.
Older cats may also begin losing their sense of smell, which can lower their appetite. Switching from dry food to wet food or adding wet toppers to your cat food can help stimulate your feline’s appetite. You may even want to warm wet cat food to increase the odor.
Your vet may recommend therapeutic food, which is formulated for weight gain. Your vet may also be able to prescribe an appetite stimulant to encourage your older kitty to eat more.
