Call a vet today

Call your vet today for advice – don't wait until signs appear. When ingested, paintballs can cause severe poisoning and can be life-threatening in cats, although this toxicity is uncommon.

What to do right now

  1. Call your vet or the nearest emergency vet.
  2. Note what was eaten, how much and when.
  3. Bring the packaging.
  4. Keep your cat calm.
  5. Remove what is left.

Don't

  • Do not make your cat vomit unless a vet tells you to.
  • Do not give any human medicine.

Why it can be dangerous

In cats, ingestion can rarely result in severe poisoning, and this toxicity can be life-threatening.[1] The components inside a paintball are osmotically active and can pull free water into the intestinal tract.[1]

Signs to watch for

  • Vomiting
  • Diarrhea
  • Tremors
  • Seizures
If your pet is struggling to breathe, has collapsed, is having a seizure or can't stand up: go to the nearest vet now.
