5 Plants That Are Toxic to Cats and Could be in Your Home or Garden

If you’re a cat owner, you probably take great care to provide a safe environment for your pet. However, some plants that seem harmless in your home or garden can pose serious risks to your cat’s health. Cats are naturally curious creatures, and even indoor cats might nibble on houseplants. In this blog, we’ll discuss five common plants that are toxic to cats, what symptoms to watch for, and how to keep your cat safe from them. If you suspect your cat has ingested a toxic plant, call us at Limerick Veterinary Hospital at (610) 489-2848 or book an appointment online for advice.

Lily (Lilium species)

Lilies are one of the most dangerous plants for cats. All parts of the plant, including the flowers, leaves, and pollen, are toxic. Even a small amount can cause severe kidney damage in cats. The most common types of toxic lilies include Easter lilies, tiger lilies, and daylilies, all of which may be found in gardens or floral arrangements.

If your cat comes into contact with lilies, you may notice symptoms such as vomiting, lethargy, and a decrease in appetite. Ingesting lilies can lead to kidney failure within a few days if not treated quickly. Early signs of kidney failure include increased thirst and urination. If you suspect your cat has eaten any part of a lily plant, seek veterinary attention immediately. The sooner treatment begins, the better the chances of preventing permanent kidney damage. Keeping lilies out of your home or garden is the best way to avoid this risk.

Aloe Vera

Aloe vera is popular for its healing properties and is often used in lotions, gels, and skincare products. Many people also keep aloe vera plants in their homes for decoration or medicinal use. However, aloe vera is toxic to cats if ingested. The gel inside the leaves, while soothing for human skin, contains compounds called saponins and anthraquinones, which can cause serious issues for cats.

Common symptoms of aloe vera poisoning include vomiting, diarrhea, and changes in color of the urine. Cats might also show signs of lethargy or tremors. If your cat has chewed on an aloe vera plant, contact your vet right away. It’s a good idea to keep aloe vera plants out of reach or consider moving them to a room your cat doesn’t access. If you have aloe vera products in your home, store them securely to avoid accidental exposure.

Philodendron

Philodendrons are often used as indoor plants because of their ability to thrive in low light. Unfortunately, they are toxic to cats. The plant contains insoluble calcium oxalates, which can cause irritation to your cat’s mouth, tongue, and throat. Even a small bite from the plant can lead to painful symptoms.

Signs that your cat may have ingested philodendron include drooling, pawing at the mouth, vomiting, and difficulty swallowing. These symptoms occur because the plant’s toxins create a burning sensation in the mouth and throat. While philodendron poisoning is rarely fatal, it can still cause significant discomfort. If you notice any of these symptoms, contact your vet. To protect your cat, it’s best to avoid having philodendron plants in your home or place them in areas that are completely out of reach.

Dieffenbachia (Dumb Cane)

Dieffenbachia, also known as dumb cane, is another common houseplant that is toxic to cats. Like philodendron, dieffenbachia contains calcium oxalates that can cause oral irritation. When chewed, the plant releases these compounds, leading to painful symptoms similar to those caused by philodendron ingestion.

If your cat has come into contact with dieffenbachia, you may notice symptoms such as drooling, vomiting, or difficulty eating. The plant can also cause swelling in the mouth or throat, making it harder for your cat to swallow. In some cases, dieffenbachia ingestion can cause difficulty breathing if swelling becomes severe. If you suspect your cat has been exposed to this plant, seek veterinary care promptly. To keep your cat safe, it’s best to avoid keeping dieffenbachia in your home, especially if your cat is known for nibbling on plants.

Azalea (Rhododendron species)

Azaleas are beautiful flowering shrubs that are often found in gardens, but they are highly toxic to cats. All parts of the plant, including the flowers, leaves, and stems, contain grayanotoxins, which can disrupt the normal function of a cat’s muscles and heart.

Symptoms of azalea poisoning in cats include vomiting, drooling, diarrhea, and weakness. More severe signs include a drop in blood pressure, abnormal heart rhythms, or even seizures. Ingesting a large amount of azalea can be fatal if not treated quickly. If your cat shows any of these signs after being around azaleas, contact your vet immediately. We recommend avoiding azaleas in your garden if you have cats, as even outdoor plants can pose a risk if your cat has access to them.

What to Do If Your Cat Ingests a Toxic Plant

If you suspect that your cat has eaten any of these plants—or any plant you’re unsure about—call your veterinarian or a pet poison hotline right away. The faster your cat receives treatment, the better their chances of recovery. When you call, try to provide as much information as possible, such as the type of plant your cat may have ingested and any symptoms you’ve noticed.

Keep a close eye on your cat for signs of poisoning, which can vary depending on the plant but generally include vomiting, drooling, lethargy, and changes in appetite or behavior. In severe cases, you may notice more serious symptoms like difficulty breathing or seizures. If your vet recommends bringing your cat in for treatment, act quickly to prevent further complications.

Preventing Plant Toxicity in Cats

The best way to prevent plant toxicity is by making sure the plants in your home or garden are safe for cats. Take the time to research any new plants you’re considering bringing into your home, and double-check that they’re non-toxic to cats. If you already have plants and you’re not sure if they’re safe, it’s worth investigating. Even if your cat doesn’t usually chew on plants, it’s better to be cautious.

In addition, try to keep any known toxic plants out of areas where your cat spends time. Hanging plants, tall shelves, or outdoor gardens that are fenced off can help reduce the risk of your cat coming into contact with toxic plants.
