What Should You Do if Your Pet Won’t Eat After Surgery?
Your pet just came home from surgery, and now they’re turning their nose up at food. Don’t panic or ignore their behavior; just keep monitoring for now. At Blue Lake Animal Hospital, we know that appetite changes after surgery are quite normal, at least to a certain point.
If your pet isn’t eating immediately after a surgery:
- Recognize what’s normal vs. concerning
- Look for signs of pain or nausea
- Try safe ways to encourage eating
If your pet continues to refuse food for more than a day or develops more severe symptoms, you should call your vet for further assistance.
Is Your Pet’s Appetite Loss Normal?
Not all post-surgery appetite changes are red flags.
Signs of normal appetite loss include:
- Skipping one or two meals in the first 24 to 48 hours
- Eating less than usual while anesthesia wears off
- Showing mild disinterest in food, but drinking water
Concerning signs include:
- Refusing food for more than 48 hours
- Not drinking water at all
- Significant lethargy alongside skipped meals
- Vomiting or gagging
Anesthesia temporarily slows digestion and dulls the appetite. A brief pause in eating should be expected. Anything beyond one to two days, however, deserves attention.
How to Tell If Pain or Nausea Is to Blame
Your pet can’t tell you that they don’t feel well. You have to be aware of the signs.
Signs of nausea can include:
- Drooling or lip-licking
- Gagging without producing vomit
- Restlessness or repeated swallowing
Signs of pain:
- Whimpering or vocalizing when touched
- Hunching over or guarding the surgical site
- Reluctance to move or change positions
If you notice any of these alongside a refusal to eat, the issue is likely not just appetite. Something else may need to be addressed.
Safe Ways to Encourage Eating After Surgery
After surgery, your pet’s appetite will take time to recover, so start small. You don’t need to offer a full bowl right away.
- Warm the food slightly: Heating wet food brings out the smell, which can help stimulate appetite
- Hand-feed small amounts: Sometimes a little direct encouragement goes a long way
- Keep the environment calm: Stress suppresses appetite, so keep noise and activity low near your pet’s recovery space
- Follow discharge instructions: Your vet may have recommended a specific feeding schedule—be sure to stick to it
Never force-feed your pet or offer rich, fatty foods after surgery. These can worsen nausea and slow recovery.
When Should You Call Your Vet After Surgery?
Certain circumstances shouldn’t be treated as “wait and see” situations. Call your vet if your pet has not eaten anything for more than 48 hours, is vomiting repeatedly, shows signs of being in significant pain, or has a swollen, red, or oozing incision site. Contacting your veterinarian is always the right move when you’re unsure. It’s better to check in early than to wait too long.
