What To Do If Your Pet Eats Something Toxic 

Don’t panic.

Note what and how much was eaten.

Call your vet or a pet poison hotline.

Follow instructions exactly—do not induce vomiting unless told to.

Build a Safer Home for Your Pet 

Petproofing isn’t just about food. Make sure trash cans are secured, counters are clear, and toxic plants are out of reach. Small changes add up to a much safer life for your cat or dog.

❓ FAQ

Q: Can one grape really hurt a dog?

A: Yes. Even a single grape can trigger kidney failure in some dogs. Size and breed don’t guarantee safety—avoid grapes entirely.

Q: Are all human snacks unsafe for pets?

A: No, but many common ingredients (onion powder, xylitol, chocolate) are dangerous. When in doubt, stick to plain, singleingredient pet treats.

Q: My cat ate a lily leaf—what now?

A: Treat this as an emergency. Call your vet immediately. Lily toxicity in cats progresses quickly and can be fatal without treatment
