What It Is
Shampoos contain surfactants and fragrances that cause gastrointestinal irritation if ingested. Human and dog shampoos are not formulated for cats and may contain ingredients that are harmful.
Why It May Be Harmful
The toxic principle in shampoo is surfactants (anionic and nonionic detergents). Shampoos and soaps contain surfactants that cause gastrointestinal irritation and foaming. Ingestion typically causes vomiting, drooling, and diarrhea. Concentrated products may be more toxic.
Signs of toxicity may include:
- Vomiting
- Drooling
- Diarrhea
- Loss of appetite
- Lethargy
- Abdominal pain
- Foaming at the mouth
Timeline: Signs typically develop within a few hours.
Usually mild to moderate. Most recover with supportive care.
What to Do If Your Cat Eats It
- Contact a veterinarian or animal poison-control service for guidance.
- Remove any remaining substance from your cat's reach.
- Offer fresh water if your cat is willing to drink.
- Monitor for signs and contact a veterinarian if they develop or worsen.
Information to have ready when you call:
- Your cat's age, approximate weight, and any health conditions
- The name or type of shampoo and the estimated amount consumed
- When the exposure likely occurred
- Any current symptoms your cat is showing
- The product packaging or a photo of the plant if applicable
If only a small amount was licked and your cat shows mild drooling, offer water and contact a veterinarian for guidance.
When to Contact a Veterinarian
Contact a veterinarian or animal poison-control service immediately if your cat may have been exposed to shampoo. Do not wait for symptoms to develop.
Emergency signs that require urgent veterinary attention:
- Persistent vomiting
- Difficulty breathing if aspirated
- Severe drooling
- Lethargy or collapse
- Dehydration
Non-urgent follow-up: If only a small amount was licked and your cat shows mild drooling, offer water and contact a veterinarian for guidance.
