Bleach, antifreeze, illicit substances, and many medications meant for humans are well known for the deadly risks they pose to animals. But other surprising items around the house might be lethal.

Here’s our list of 7 unexpected things around the house that can be deadly to animals:
1. Rogaine (Minoxidil)
This common treatment for hair loss is extremely toxic to animals. If ingested—or even absorbed through the skin—minoxidil can cause heart issues, low blood pressure, and even death. Always store minoxidil in a secure location, out of reach of curious noses.
2. Lilies
Many species of lilies are deadly to cats. Ingesting even a small amount of any part of the plant—flowers, leaves, or pollen—can cause kidney failure and even death. If you share your home with cats, avoid lilies entirely.
3. Teabags (or coffee grounds)
Caffeine can be lethal to animals. Consuming moderate amounts of coffee grounds, tea bags, or even a few diet pills can cause death—especially for small animals like rabbits.
4. Xylitol
This sugar substitute, which you find in items like sugar-free gum, is toxic to dogs—as it can cause seizures and liver failure. Make sure to read labels carefully before giving something to your animal companions.
5. Non-Stick Cookware (Teflon)
Teflon-coated pans release toxic fumes that can be fatal to small animals—especially birds. So, if you have birds in your home, it’s safest to avoid using Teflon cookware.
6. Playdough
Homemade playdough can be deadly for dogs. The biggest concerns? Salt and cream of tartar. Cream of tartar contains compounds like those found in grapes, which can lead to kidney failure if a dog eats too much. And store-bought playdough is packed with high amounts of salt—which can trigger life-threatening neurological problems.
7. Essential Oils and Liquid Potpourri
Essential oils and liquid potpourri contain dangerous chemicals for cats, and kittens are even more sensitive to their effects. Wintergreen oil, peppermint oil, and citrus oil are just some of the oils that contain phenols toxic to cats, so do your research before bringing any fragrances into your home.
What to Do After Accidental Ingestion
- Call your veterinarian or the nearest emergency clinic immediately.
- Determine what your animal companion ingested and when they ate it.
- Keep the item close in case the vet needs information like the brand name, ingredients, or other details.
