If there is a change in your pet’s appetite due to some kind of health issue, your pet has no way to tell you what’s going on. That’s why it’s important to measure your pet’s food, and pay attention to how often and how much your pet is eating.

A change in appetite, especially for more than a day or two, may be a reason for concern in pets, and could be caused by a variety of medical conditions. Determining what the cause is and what needs to be done will require a trip to your veterinarian.

She’s Just Not Eating Like She Used To

Young animals require vast amounts of caloric intake in comparison to their size so they can grow and mature. As they grow, their appetite will change, slowing down as they develop an adult metabolism.

If a young animal has suddenly lost their appetite, it’s time to get them to the vet! The same goes for an adult animal who has suddenly stopped eating or begun to eat very little. Sudden loss of appetite can have many causes ranging from a blockage to an infection or a more chronic issue. Different tests can be performed when needed to help your veterinarian determine which possible issues may be causing this symptom in your pet.


He Just Won’t Stop Eating

A sudden increase in appetite, called polyphagia, can also be a cause for concern. This may be a normal development if your pet has recently been getting more exercise, but it’s more concerning in an animal whose activity level hasn’t changed, especially as they get older.

Diabetes can manifest as an increased appetite, generally with an increase in drinking and urination as well. Other possible causes of polyphagia include poor food absorption due to inflammation of the digestive tract, thyroid issues in cats, or simply a change to a food that your pet is particularly fond of.

If your pet’s appetite has suddenly changed, make an appointment with your veterinarian to find out the cause and determine the best course of action.
