So, how can it affect your pet if it ingests a part of Monstera? 

If your cat eats a part of the Monstera, it can irritate its mouth and stomach. Sometimes, it can cause damage to the walls of the stomach that result in vomiting and drooling. 

Cat’s life is not at risk if it has not eaten plants in larger quantities. The good thing is that monstera causes irritation in the mouth of the cat right after it takes a bite, so it won’t encourage the cat to eat more.


You might be curious what makes Monstera unsafe for cats, here is the detailed answer to it!

Calcium Oxalate Crystals?

The crystals of calcium oxalate are composed of calcium and oxalate, sharp and needle-like points. That is why they cause irritation in the mouth,throat and even stomach resulting in the damage of the inner walls of the stomach.

They are pointed so they get embedded in the tissues of the stomach. 

This is why it is advisable to wear gloves before handling Monsteras especially while pruning or cleaning.

These pointed crystals actually prevent monstera plants from being eaten by pets.

But the plant also produces fruits that are edible and completely safe when ripe.

Fruit when eaten by animals or humans, it helps in the dispersion of the seeds of the Monstera.

Does The Whole Monstera Plant Contain Calcium Oxalate Crystals?

Crystals are present in all parts of the plant including stem, root, leaves, shoots, and even the unripe fruit. 

Therefore it is advised to keep cats away from the plant as it can irritate their health.


If you’re in doubt that your cat has been poisoned by Monstera, observe these few things:

  • If your cat is pawing due to mouth or skin irritation, it can be due to monstera poisoning.
  • If your cat’s mouth shows any swelling inside, or tongue or lips swelling, it can also be another reason.
  • In extreme cases, your cat’s throat could swell and it makes it difficult for it to breathe properly.
  • If you observe vomiting, or drooling, take your pet to the vet immediately.

In most of the cases, Monstera poisoning does not kill the cat or any other pet. 

But, if your cat ingests the plant in larger quantities, it can get it to serious trouble.

The best way to prevent your pet cat from eating monsteras is to keep them away. You can keep them away by distracting them to other things or limiting their access to the plant.

Here are a few ways to do so!

Use Cat Deterrents

Deterrents keep pets away and ultimately protects them from getting poisoned. The deterrents make the plant smell bad or less appealing so it does not go near the plant.

Let’s take a look at the common deterrents used for this purpose.


Water is a good deterrent for preventing cats coming near the Monstera plant. If your cat gets friendly with the plant, spray the cat with water. In this way they’ll learn that if they get closer to the plant, they’ll become wet.

This is a simple yet effective way to keep pets away from the poisonous plants.

Other Repellents

Other than water, you can also use citrus fruits to keep the pets away from Monstera. You can use orange, lemon, and citrus peel in the pot and squeeze a little on the boundary of the pot.

You can also use mustard and red pepper to repel cats. 

If you have rosemary in your garden, put it around the Monstera, it will keep the cat away as they hate the smell.

If all this couldn’t work, use pet deterrent spray to keep your cat or other pets away.

Mulching top soil

Another great way to keep the cats away from your Monstera is to add something to the top of the soil in your plant’s pot. 

Cats don’t like pine cones, bark, and stones. You can try any of these. 

Keep Plants Out Of Reach Of Your Cat

If your cat does not climb high, you can place your Monstera’s pot top on the shelf. You may also hang it as it is a great way to grow Monstera around your home.

You can also place barriers like chicken wire around the plant to prevent cats from entering that area. 

If you have a space that is out of reach of your pets, that’s the best way to keep them away from poisonous plants. 

Tip: Clean the dropped leaves from the area around Monstera, so that your cat does not perceive it as a snack.

Keep Them Distracted

If your cat has not enough toys to play with, and other distractions, it is more likely that it’ll go around your plants. 

So, keep them distracted with toys, and other activities so that they don’t play with your plants.

You can also keep your cat busy with Youtube videos to distract it. 

Also, if cats are not given attention and enough food, they try to find it in other things including plants.

Use Fresh Litter Tray

Another reason that has been observed is cats disturb plants when they are fresh, because they perceive the soil as their litter tray.

If you change the litter tray often, and still your cat enters the pot, it means your cat does not like its litter tray.

There can be other health issues behind your cat entering the Monstera’s pot. So, you can visit your vet if you observe something continuously for days.
