Why Is My Cat Throwing up?
If your cat is throwing up, there could be many possible causes — some mild, some more serious. Here’s a breakdown to help you figure out what might be going on:
???? Common & Usually Minor Causes:
1. Hairballs
- Cats groom themselves constantly and swallow loose fur.
- It can clump in their stomach and come back up as a hairball.
- Normal occasionally, but frequent hairballs may need attention (grooming, diet change).
2. Eating Too Fast
- Some cats inhale their food too quickly, then vomit it right back up — often whole and undigested.
- Try a slow-feeder bowl or feeding smaller portions more often.
3. Dietary Indiscretion
- A sudden change in food, treats, or human food can upset their stomach.
- Stick to consistent, high-quality food and introduce any changes gradually.
⚠️ More Concerning Causes:
4. Food Allergies or Intolerances
- Some cats can’t tolerate ingredients like dairy, grain, or certain proteins.
- Vomiting, diarrhea, or itchy skin may be signs.
5. Intestinal Parasites
- Worms or protozoa can irritate the GI tract.
- Vomiting plus weight loss, bloating, or diarrhea may suggest this.
6. Toxic Ingestion
- Some houseplants (like lilies), string, ribbon, rubber bands, or human medications are dangerous or fatal.
- If you suspect ingestion, see a vet immediately.
7. Chronic Illness
- Ongoing vomiting (especially with weight loss, lethargy, or changes in thirst/appetite) can point to:
- Kidney disease
- Hyperthyroidism
- Diabetes
- Inflammatory bowel disease (IBD)
???? When to See a Vet Immediately:
- Vomiting more than once or twice a day
- Blood in vomit
- Lethargy, weakness, diarrhea, or dehydration
- Vomiting along with no appetite or weight loss
- If your cat is a kitten or senior
Bottom line:
Occasional vomiting in cats can be normal (especially hairballs), but frequent or severe vomiting is a red flag. A vet can run tests to find out if it’s dietary, parasitic, or a more serious health condition.
