10 Common Cat Poisons You Need to Know About

As a cat owner, you undoubtedly take great care to ensure that your furry friend is healthy and happy. However, despite your best efforts, your cat may come into contact with something toxic.

It’s vital to be aware of the most common cat poisons so that you can take steps to prevent accidental poisoning. In this article, we’ll explore the top ten most common cat poisons.

We’ll look at how they can affect your cat, how to prevent exposure, and what to do if your cat has ingested a toxic substance.

Top 10 Cat Poisons

1. Flea and Tick Products

Flea and tick products designed for dogs can be deadly if applied to cats.

Pyrethroid insecticides, such as permethrin, are commonly found in dog flea and tick products. Unfortunately, they can cause muscle tremors, seizures, and death in cats.

Always read labels carefully and apply the product as directed. If you have both dogs and cats in your home, be sure to keep them separated until the product dries.

2. Topical Insecticides

Other types of topical insecticides are toxic to cats too.

These products, such as flea powders, shampoos, and sprays, can also cause seizures, tremors, and incoordination in cats. To avoid accidental poisoning, only use products that are labeled for cats and always follow the instructions carefully.

3. Venlafaxine (Effexor)

Venlafaxine is an antidepressant used to treat depression and anxiety in humans.

Unfortunately, cats are sensitive to this medication and can develop symptoms such as vomiting, diarrhea, seizures, and tremors if they ingest it. Always keep medications safely stored out of reach of pets and never give your cat medication meant for humans.

4. Glow Sticks and Glow Jewelry

Glow sticks and glow jewelry are popular among children and adults alike.

However, these products can be dangerous to cats. If your cat chews on a glow stick or jewelry, they may experience drooling, vomiting, agitation, and difficulty breathing.

Be sure to keep these items out of your cat’s reach. 5.


Lilies are popular flowers, but they are toxic to cats. Every part of the plant, even the pollen, can cause kidney failure in cats.

Symptoms can include vomiting, lethargy, decreased appetite, and increased thirst. If you have cats, avoid keeping lilies in your home or garden.

6. Liquid Potpourri

Liquid potpourri is a decorative item used to freshen up a room.

Unfortunately, it can be hazardous to cats. Liquid potpourri contains essential oils and corrosive detergents that can cause chemical burns in a cat’s mouth, throat, and stomach if they ingest it.

Be sure to keep liquid potpourri safely away from your cat. 7.

Non-Steroidal Anti-Inflammatory Drugs (NSAIDs)

NSAIDs are commonly used to reduce inflammation and pain in humans. However, some NSAID products, such as ibuprofen, can be toxic to cats.

Symptoms of NSAID poisoning in cats include vomiting, diarrhea, decreased appetite, and lethargy. Always follow the label instructions when giving your cat any medication and never give your cat human medication unless directed by a veterinarian.

8. Acetaminophen (Tylenol)

Acetaminophen is a common medication used to relieve pain and reduce fever.

However, it can be toxic to cats and can cause liver damage, anemia, and difficulty breathing. Never give your cat acetaminophen, and be sure to store all medications out of reach of your cat.

9. Anticoagulant Rodenticides (Rat Poison)

Anticoagulant rodenticides, or rat poison, work by preventing the blood from clotting.

Unfortunately, these products can be toxic to cats too. If your cat ingests rat poison, they may experience lethargy, bleeding from the nose or gums, and difficulty breathing.

If you suspect your cat has ingested rat poison, seek veterinary care immediately. 10.


Amphetamines are commonly used to treat attention deficit hyperactivity disorder (ADHD) in humans. However, they are toxic to cats and can cause vomiting, fever, seizures, and death.

Always keep human medications safely stored out of reach of pets.

Preventing Cat Poisoning

The best way to prevent accidental cat poisoning is to be aware of potential hazards. Keep toxic substances, such as medications, household cleansers, and rat poison, safely stored out of your cat’s reach.

If you have plants in your home, make sure they are not toxic to cats. Be sure to read labels carefully before applying flea and tick products to your pets, and always use products specifically labeled for cats.

If you suspect your cat has ingested something toxic, seek veterinary care immediately. Early treatment can save your cat’s life.


Being aware of the most common cat poisons can help you take steps to prevent accidental poisoning. Keep all toxic substances safely stored away from your cat, and be sure to read labels carefully before using any product on your pet.

If you suspect your cat has ingested a toxic substance, seek veterinary care immediately. By being prepared, you can help keep your cat safe and healthy.

In conclusion, the top ten most common cat poisons include flea and tick products, topical insecticides, prescription medication, glow sticks, lilies, liquid potpourri, NSAIDs, acetaminophen, rat poison, and amphetamines. Poisoning can be prevented through awareness and careful storage of toxic substances, being mindful of cat sensitivities, and taking early action if you suspect your cat has ingested something toxic.

By taking these steps, you can help keep your cat safe, healthy, and happy.
