Senior Pet Appetite

James Byler • July 18, 2025

As pets age, changes in their behavior, energy levels, and appetite are common. One of the most noticeable changes pet parents often observe is a shift in senior pet appetite. While some loss of appetite in older pets can be normal, it’s essential to understand what’s expected and when it may signal an underlying health issue.



Why Senior Pets Eat Less

Senior pets—typically classified as dogs over seven and cats over ten years old—may experience a natural decline in appetite due to a slower metabolism, reduced activity levels, or changes in their sense of taste and smell. Dental issues, such as gum disease or tooth pain, are also common culprits, making it uncomfortable for pets to chew and enjoy their meals.


Medical Reasons Behind Appetite Changes

If your older pet refuses food, eats less, or shows a sudden change in eating habits, it could indicate more serious concerns like kidney disease, liver problems, arthritis pain, cognitive decline, or even cancer. Any abrupt or sustained appetite loss should be evaluated by a veterinarian.


Encouraging Healthy Eating in Senior Pets

To maintain a healthy diet in senior pets, offer high-quality, age-appropriate food that’s easy to chew and digest. Warming food slightly, adding broth, or introducing a vet-approved appetite stimulant may help. Keeping a regular feeding schedule and providing a calm, stress-free environment can also encourage eating.


When to See a Vet

If your senior pet refuses food for more than 24–48 hours, or if weight loss, vomiting, diarrhea, or lethargy accompanies appetite changes, consult your veterinarian. Early diagnosis can make a significant difference in managing age-related health conditions.

Supporting your senior pet’s appetite is key to helping them live a comfortable and happy life in their golden years. Stay observant, offer love and care, and don’t hesitate to seek professional guidance when needed.
