Is Monstera Toxic to Cats? [How to Save Pets]

Monstera is reigning in many households flaunting its exotic evergreen foliage, but it doesn’t go along with cats, for it is toxic. 

This alluring beauty hides its poisonous dark nature right under your nose.

According to the ASPCA, Monstera plants are toxic to cats due to calcium oxalate crystals in all parts of the plant. Upon ingestion, it causes oral irritations, gastrointestinal upset, excessive drooling, and in critical conditions, kidney damage.

Don’t worry, even if your cat eats any part of the Monstera plant, or perhaps any of your pets eats them, as it can be treated quickly.

Is Monstera Safe for Cats?

The American Society for Prevention of Cruelty to Animals (ASPCA) has listed different plant species, including Monstera adansonii, and Monstera oblique that is toxic to cats. 

Monstera plants contain insoluble calcium oxalate crystals (needle-like raphides) throughout their roots, stems, and leaves, and that causes a severe burning sensation and irritation in cats, dogs, and even humans upon ingestion. 

Monstera plants are moderately toxic to cats, but the level of poisonous effect elevates with the amount your pet nibbles on.

Beware: Monstera is mildly toxic to cats, but it can cause pets to suffer pain.

Generally, ingestion of Monstera in smaller amounts isn’t fatal, but it will make your cat suffer, leaving a terrible experience.

These needle-like raphides may not be a ‘toxin’ but rather an irritant with discomfort and a source of pain to your pets.

What Happens if a Cat Eats a Monstera?

Your cats are more likely to stop eating the plant as soon as the bitter taste and burning sensations on their tongue kick-off.

The insoluble calcium oxalate crystals can damage the sensitive tissues in the cat’s mouth, causing intense oral pain and swelling.

Depending on consumption, these symptoms will develop within a few minutes or after 2-3 hours.

The only way out from the toxicity is to act upon the situation immediately.

Additionally, swollen tongue and throat create difficulty eating and obstruct the air passages from the throat to the lungs. 

However, Monstera with toxins cannot trouble cats with major issues, including kidney and other organ failures. 

If your dogs eat the Monstera plant, the symptoms resemble that of a poisoned cat. 

But remember other common cat problems: food poisoning or parasitic infection also exhibits similar symptoms.

So, narrow down the main culprit before making a Monstera poisoning as a final verdict.

  • Wrap your cat with a towel to keep them from struggling.
