Pet Not Eating or Drinking: Causes, Warning Signs & What to Do
Author: Dr. Stevens
Has your pet stopped eating or drinking? It can be alarming when your pet suddenly loses interest in food or water. In many cases, it’s their way of telling you something isn’t right—and ignoring it can lead to more serious problems.
This guide breaks down common causes, warning signs, and when to seek veterinary care.
Why Is My Pet Not Eating or Drinking?
When your pet stops eating or drinking, there may be an underlying issue. Common causes include:
- Illness or infection (gastrointestinal upset, pancreatitis, fever, kidney or liver disease)
- Dental problems causing pain while eating
- Stress or anxiety due to changes in environment or routine
- Foreign object or blockage from ingesting something inappropriate
- Diet or routine changes
- Heat or weather changes affecting appetite
Warning Signs to Watch For
Loss of appetite is often accompanied by other signs that something may be wrong:
- No water intake for more than 12–24 hours
- No appetite for more than 24 hours
- Vomiting or diarrhea
- Lethargy or hiding
- Weight loss
- Pale gums
- Dry nose or sunken eyes (signs of dehydration)
Important: Puppies, kittens, senior pets, and small breeds can decline quickly. If you notice changes, don’t wait.
When to Seek Veterinary Care
Contact a veterinarian if your pet:
- Has not eaten for 24 hours
- Has not had water in 12–24 hours
- Is vomiting, lethargic, or showing signs of illness
- May have swallowed something they shouldn’t
- Is very young, old, or medically fragile
Never give human medications or home remedies without veterinary guidance.
