Are Wandering Jew Plants Poisonous to Cats?
Yes, wandering Jew plants (Tradescantia species) are mildly toxic to cats. If your cat chews or ingests any part of this plant, it can cause skin irritation, drooling, vomiting, or diarrhea. The good news is that severe poisonings are rare, but it is still important to know the risks and how to keep your cat safe.
What Is a Wandering Jew Plant?
The wandering Jew plant is a popular houseplant known for its trailing vines and colorful leaves. Common varieties include Tradescantia zebrina (purple and silver stripes), Tradescantia fluminensis (small green leaves), and Tradescantia pallida (deep purple). These plants are native to Central and South America and are often grown in hanging baskets or as ground cover. They are easy to care for, which makes them a favorite among indoor gardeners.
The name "wandering Jew" comes from an old folk tale, but many growers now prefer the common name "inch plant" or simply Tradescantia. The plant grows quickly and can thrive in low light, making it a common choice for homes and offices. However, if you share your home with a cat, you need to know how this plant can affect your pet.
Are Wandering Jew Plants Poisonous to Cats?
Yes, wandering Jew plants are considered mildly toxic to cats. The sap inside the leaves and stems contains compounds that can irritate your cat’s skin and digestive system. According to the ASPCA (American Society for the Prevention of Cruelty to Animals), Tradescantia species are listed as toxic to cats and dogs.
The exact toxic component is not fully identified, but it is thought to be calcium oxalate crystals or other irritating substances. When a cat bites the plant, these tiny crystals can cause immediate pain, swelling, and burning in the mouth. This often stops the cat from eating more, but some cats may still swallow enough to cause sickness.
It's important to remember that "toxic" does not always mean "deadly." Most cats that nibble a wandering Jew plant will experience only mild symptoms. However, every cat is different, and some may have a stronger reaction, especially if they eat a large amount or have a sensitive stomach.
What Happens If My Cat Eats a Wandering Jew Plant?
If your cat eats part of a wandering Jew plant, you may notice symptoms within minutes to a few hours. The most common signs include:
- Drooling or foaming at the mouth – due to irritation from the crystals.
- Vomiting – often about 30 minutes to an hour after eating.
- Diarrhea – can be mild but may last a day.
- Loss of appetite – because of mouth discomfort.
- Skin irritation – if the sap touches the fur and skin, you may see redness, itching, or small bumps.
- Pawing at the mouth – a sign of oral pain.
In rare cases, if a cat eats a very large amount, the vomiting and diarrhea can lead to dehydration. This is more likely in kittens or older cats with weaker immune systems. Severe reactions like difficulty breathing or tremors are not typical with wandering Jew plants, but they are possible if your cat has an allergy or eats another toxic plant at the same time.
Most symptoms resolve on their own within 12 to 24 hours, especially if the cat only had one or two bites. However, it is always best to contact your veterinarian if you see any concerning signs.
How to Keep Your Cat Safe from Wandering Jew Plants
The safest option is to remove the plant from your home if you have a curious cat. But if you love the plant and want to keep it, here are practical steps:
- Place the plant in a hanging basket or high shelf that your cat cannot reach. Cats can jump, so make sure it is far from any jumping surface like a table or cat tree.
- Use a cat deterrent spray on the leaves. Many sprays have a bitter taste that discourages chewing. Look for sprays made with safe ingredients like citrus or essential oils (but check that the oil is not toxic to cats in large amounts).
- Grow the plant in a closed terrarium or glass cabinet. This both protects your cat and keeps the humidity high for the plant.
- Provide your cat with cat-safe plants like cat grass or catnip to distract them from the wandering Jew.
- If you notice your cat showing interest, trim back trailing vines so they are out of reach.
Another option is to choose a different houseplant that is non-toxic. Many beautiful plants are completely safe for cats. For example, you can replace your wandering Jew with a spider plant, Boston fern, or prayer plant – all of which have no known toxicity to cats.
If you decide to buy a cat-safe alternative, consider a spider plant in a basket – it is easy to grow and non-toxic. Or if you want colorful trailing foliage similar to wandering Jew, a maranta prayer plant is a great choice.
What Should I Do If My Cat Eats a Wandering Jew Plant?
If you see your cat eating the plant, do not panic. Follow these steps:
- Remove the plant from your cat’s reach and check how much was eaten.
- Rinse your cat’s mouth gently with water if you can do it safely. This helps remove any remaining sap or crystals.
- If your cat has vomited, collect a sample in a bag in case the vet wants to see it.
- Call your veterinarian or the nearest animal poison control center. In the US, you can call the ASPCA Animal Poison Control Center at (888) 426-4435 (a fee may apply).
- Watch your cat for symptoms. If vomiting or diarrhea lasts more than 24 hours, or if your cat seems very weak, take them to a vet.
Do not try to make your cat vomit unless a vet tells you to. Some plants cause more damage when brought back up. Also, do not give your cat any home remedies like milk or hydrogen peroxide. Plain water is the only safe thing to offer.
It is a good idea to keep a cat first aid kit at home. It should include a syringe for water, a blanket, and contact numbers for your vet and poison control. Being prepared can save time if an emergency happens.
Are There Safe Alternatives for Cat Owners?
Yes, there are many houseplants that are completely safe for cats. Some even help clean the air or provide enrichment. Here is a simple comparison table of wandering Jew and common cat-safe plants:
| Plant | Toxicity to Cats | Care Level | Notes |
|---|---|---|---|
| Wandering Jew (Tradescantia) | Mildly toxic | Easy | Irritating sap, avoid in cat homes |
| Spider Plant (Chlorophytum) | Non-toxic | Easy | Produces pups, cats may chew leaves but safe |
| Boston Fern (Nephrolepis exaltata) | Non-toxic | Moderate | Likes humidity, great for hanging |
| Maranta Prayer Plant | Non-toxic | Moderate | Colorful leaves, moves at night |
| Peperomia (various) | Non-toxic | Easy | Many leaf shapes, non-toxic to cats |
If you already have a wandering Jew and want to keep it, consider placing it in a room that your cat cannot enter. But for most cat owners, choosing a non-toxic plant gives peace of mind. You can find many safe options at garden centers or online. For example, a Boston fern in a hanging basket is a lush, pet-friendly addition to your home.
Remember that even non-toxic plants can cause mild tummy upset if your cat eats a lot. The key is to offer cat grass as a safe chewing option and keep all houseplants out of reach if your cat is a determined nibbler.
Does the “Wandering Jew” Name Affect Toxicity?
No, the name itself does not change the plant’s chemistry. However, some people use the name “wandering Jew” for different plants in the Tradescantia genus. All Tradescantia species are considered similarly toxic. Sometimes other unrelated plants like the “wandering Jew” (in some regions) might be a different species, but for houseplant purposes, it is almost always a Tradescantia. When in doubt, check the scientific name. The safest rule is: if it looks like a trailing inch plant with purple and silver stripes, it is likely toxic to cats.
How Toxic Is Wandering Jew Compared to Other Common Houseplants?
Wandering Jew is considered mildly toxic, similar to plants like pothos or philodendron. These plants also contain calcium oxalate crystals that cause mouth irritation. In contrast, true lilies (Lilium species) are extremely toxic to cats and can cause kidney failure even from a small nibble. So while wandering Jew is not a deadly threat, it is still one you want to avoid if you have a cat that likes to explore with its mouth.
Here is a quick checklist to help you decide what to do with your wandering Jew plant:
- ☐ Is your cat prone to chewing plants? If yes, remove the plant.
- ☐ Can you place it completely out of reach (high hanging basket, closed room)? If no, remove the plant.
- ☐ Do you have a safe alternative plant to replace it? If yes, swap it out.
- ☐ Do you have emergency vet numbers saved? If no, write them down now.
Taking a few minutes to cat-proof your home can prevent a stressful trip to the vet. If you decide to keep your wandering Jew, monitor your cat closely. You can also try a bitter apple spray for cats to deter them from the plant. Many pet owners find these sprays helpful for training cats to avoid certain areas or objects.
In summary, wandering Jew plants are mildly poisonous to cats. The risk is real but not life-threatening in most cases. The best approach is prevention: either remove the plant or keep it far from your cat. With a few simple changes, you can enjoy a green home and keep your feline friend safe.
