Not all items are highly toxic, but the list can remind pet parents of dangerous items they might have around the house. The items are listed in order of frequency, with No. 1 causing the most emergency calls to Pet Poison Helpline.

Cats: Top 10 Toxins of 2013
1. Lilies
Plants in the Lilium species, such as Easter, Tiger and Asiatic lilies, cause kidney failure in cats. All cat owners must be aware of these highly toxic plants.

2. Household Cleaners
Most general purpose cleaners (e.g., Windex, Formula 409) are fairly safe, but concentrated products like toilet bowl or drain cleaners can cause chemical burns.

3. Flea and Tick Spot-On Products for Dogs
Those that are pyrethroid based (Zodiac, K9 Advantix, Sergeant’s, etc.) cause tremors and seizures and can be deadly to cats.

4. Antidepressants
Cymbalta and Effexor topped our antidepressant list in 2013. Cats seem strangely drawn to these medications. Beware – ingestion can cause severe neurologic and cardiac effects.

Cats are even more sensitive than dogs to drugs like ibuprofen and naproxen. Even veterinary specific NSAIDs like Rimadyl and Meloxicam should be used with caution.

6. Prescription ADD/ADHD Medications
These amphetamines such as Adderall, Concerta, Dexedrine, and Vyvanse can cause tremors, seizures, cardiac problems and death.

7. OTC Cough, Cold and Allergy Medications
Those that contain acetaminophen (e.g., Tylenol) are particularly toxic, as they damage red blood cells and cause liver failure.

8. Plants Containing Insoluble Calcium Oxalate Crystals
Common houseplants like the peace lily, philodendron and pothos can cause oral/upper GI irritation, foaming at the mouth and inflammation when ingested, but severe symptoms are uncommon.

9. Household Insecticides
Thankfully, most household sprays and powders are fairly safe, but it’s best to keep curious kitties away until the products have dried or settled.

10. Glow Sticks and Glow Jewelry
These irresistible “toys” contain a chemical called dibutyl phthalate. When it contacts the mouth, pain and excessive foaming occur, but the signs quickly resolve when the cat eats food or drinks water.
