Is Rubber Plant Toxic to Cats?

If you are fond of houseplants, you probably already know that the most popular in-house tree-like plant has to be the Rubber plant.

In recent years, the Rubber plant has gained popularity because of its large and rich green foliage and low maintenance requirement.

Hence, you might wonder if any of your pets will let you have a Rubber plant as a part of your living place decor.

Is your Rubber plant, among the many lovely indoor plants, also toxic to cats?

According to ASPCA, the Rubber plant is mildly toxic to cats. The protein found in its sap causes skin irritation, gastrointestinal symptoms, and multiple organ failure.

Because of its irresistible looks, you may bring the Rubber plant to your home without knowing its toxicity.

You can make it work with your fur baby roaming all over the house.

Don’t worry, here is complete information on the Rubber plant’s toxicity from the symptoms to treatment, without forgetting the preventable ways.

Which Part of Rubber Plant is Poisonous?

If your cat eats any Rubber plant’s part, it has a high chance of experiencing drooling, coughing, vomiting, diarrhea, and a loss of appetite.

Cats are poisoned by latex, a milky sap secreted by Rubber plants.

Latex is an essential component of your plant that has a role in transporting nutrients all over the plant’s body.

The latex has proteins with antigenic properties towards anything that attacks the plant. Be it cats, insects, or pests. It is common for cats to go nibbling and playing with your houseplants.

Playing with the plant without scratching it or breaking it won’t release sap, so it is safe for your cat unless there is sap.

The sap of the Rubber tree contains a chemical called caoutchouc also called Rubber which gives the plant its name. These chemicals provide elasticity in Rubber plants.

Despite its many benefits, Caoutchouc can irritate the eyes and mucous membranes. It will induce more severe effects if eaten.

Hence, the roots, the leaves, the stem, the whole plant is toxic. Therefore, it is your job to keep your cat away from the poisonous plant.

Among the proteins, a proteolytic enzyme, commonly known as ficin and ficusin, has the antigenic property to cats.

In humans, too, it can cause allergies when in contact with skin and gastrointestinal problems when ingested.

However, according to ASPCA, the toxicity is listed as a mild one, which is treatable.

Will a Rubber Plant Poisoning Kill my Cat?

The fatality depends on the amount of latex consumed by your cat.

The toxin won’t kill your cat instantly but can cause fever and other symptoms that won’t heal unless medical attention is provided.

Hence, Rubber plant poisoning can kill your cat if the latex intake is high and there is no immediate medical attention.

The skin contact of sap from broken leaves and stem is rare in the case of cats because the fur acts as a safety blanket.

Simply washing the sap from the fur in case of contact will be enough to prevent skin irritation and allergies.

However, eyes, nose, and mouth are even more sensitive spots for your cat.

The amount of sap near to or more than 2mg will cause poisoning symptoms, and you need to take your cat to your vet as soon as possible.

The Symptoms of Rubber Plant Toxicity in Cats

When your cat is poisoned with latex of your Rubber plant that is 2mg or even less, it will take a maximum of 15-20 minutes to show the following symptoms.

The symptoms on the gastrointestinal tract and mouth region become more prominent.

In case of contact with skin, allergic reactions can be seen within seconds in most cases.

A large dose leads to severe dehydration, heart irregularities, shock, and eventually death.

First Aid for Poisoned Cats

The most important thing is that you cannot ultimately provide a cure, be it the skin contact or ingested amount; hence, you need to call your cat’s veterinarian or any veterinarian nearest to your location.

Here are some of the helplines-

You should have the following information on hand: your cat’s breed, age, sex, weight, symptoms, and the amount of toxin they ingested, if possible.

Until the vet arrives or you reach them, here are some things you can do.

1. In Case of Skin Contact

When it comes in contact with skin, the latex within the sap causes irritation, redness, dryness, and itchiness on the skin.

While playing, if your cat is exposed to sap, it will act differently. You may notice your cat scratching on the contact region.

It will start shaking the fur, body, or head. Here are some of the things you can do in such a case.

  • Call your vet and act accordingly.
  • With your clean hands, wash off the area that came in contact with latex.
  • Use a soap that you have been using to give a bath to your cat. Soap water can clean the latex properly.
  • You can also give a warm bath to wash off the toxin by asking your vet.
  • Provide well ventilation.
  • Use a blanket to keep your cat warm.
  • Feed your cat correctly and be extra careful in keeping them hydrated.
  • Do not induce vomiting without consulting the vet because skin contact is not the same as ingestion.

Here are some first aid kits you can buy and keep for such emergencies.

2. In Case of Ingestion

As soon as you find out that your cat has ingested the rubber plant sap, the immediate action should be expelling the poison out of the body to prevent its action.

Hence, try inducing vomiting ONLY after consulting your vet. Giving a little saltwater can cause nausea and induce vomiting in cats.

It is advisable not to try inducing vomit other than saltwater. Do not try putting fingers or anything inside their mouth to induce vomiting, as it may further complicate or hurt your cat.

However, your cat will start throwing up itself if poisoned. After several vomits and diarrhea, your cat becomes dehydrated.

Therefore, provide some fluids and try keeping your cat cozy until your vet arrives.

Also, here are some of the things you can do to help until the vet arrives in case of ingestion of poison.

  • If your cat is cold, wrap it up in a warm cloth.
  • Move your cat away from the rubber plant and its broken parts.
  • Check for the presence of latex in the mouth. If you see latex, try washing its mouth with clean water and wiping it carefully.
  • Do not let it spread to the nose and eyes.
  • After asking your vet, if they suggest you induce vomiting, try using warm salt water to induce vomiting.
  • If your cat is unconscious or shivering, do not induce vomiting but try keeping it hydrated if only your vet suggests.

DO NOT induce vomiting without asking any vet. DO NOT feed without asking your vet.

Diagnosis of Rubber Plant Poisoning for Cats

An electrocardiogram is used to study your cat’s heart function in case of unconsciousness.

You must provide a brief medical history of your cat to the vet. Try to calm yourself and establish well-informed communication with the vet.

Provide the information on the allergies your cat has if any. If your cat was under any medications, try not miss the information.

IMPORTANT: Take the part of the plant that your cat consumed to the vet.

Treatment of Toxicity 

After you provide first aid, observe the persistence of the symptoms again.

Since the sap is allergic, it would be possible that your cat has ingested only a small amount because sensitivity and swelling come as soon as the sap touches the mouth or nose region.

However, if your cat has ingested more of the sap, other treatments are to be done.

Give your cat foods rich in fluids to easy on the stomach.
