Peace lily plants contain calcium oxalate crystals which can be extremely harmful when you have pets. Now, these crystals are not only present in certain parts of the plant.

These toxins are present in all parts, including roots, leaves, foliage and flowers. This is why it can be dangerous for curious pets. These crystals are a powerful irritation toxin. 

Although only mildly toxic to humans, it is extremely toxic for dogs and cats.

Cats are often curious about plants and tend to play with, chew or bite the foliage of different household plants. Unfortunately, with the peace lily, you really have to be careful. 

Should your cat or kitten happen to bite or chew on these leaves, the toxic crystals are released into their mouth and can cause severe painful injuries.

This means peace lily is toxic to cats, even without them having to ingest the plant. The level of peace lily toxicity is considered mild or moderate.

Although, this depends on exposure to a toxin or how much has been ingested. 

Signs that your cat may have been exposed to the peace lily toxin includes: 

  • Burning or irritation of the mouth and tongue.
  • Excessive vomiting.
  • Increased salivation.
  • Drooling.

The peace lily is toxic to dogs and therefore also poses a risk to man’s best friend. The irritation toxin is equally as dangerous for dogs as it is for cats. 

While dogs may not be as likely to chew on leaves, which will also cause an inflammatory reaction in dogs – dogs may be likely to get a reaction when digging near the plant or from the pollen. 

Certain dogs can get an oral irritation when exposed to the pollen of the peace lily. When this pollen is licked off fur or paws, it can cause severe oral inflammation along with other symptoms. 

Common symptoms for dogs include:

  • Excessive drooling.
  • Swollen mouth, muzzle or throat. 
  • Vomiting.
  • Diarrhea.

While these symptoms would cause any pet parent to panic, it will not necessarily need you to take a trip to the vet. Often symptoms can be treated with home remedies.

However, should the symptoms persist, you should seek out medical attention. 

What to do if your pets have been exposed to Peace Lily toxin? 

The first thing to do is not panic. It can be unnerving to notice the symptoms, but they can often be treated at home. For both cats and dogs, take care to remove any leaves or plant parts from your pet’s mouth. 

Try to rinse out your pet’s mouth with water and encourage them to drink. Serving them, some ice chips can also soothe the inflammation. 

Try to clean or wash your pets’ paws and fur to remove any other irritants that may still remain. Do not try to induce vomiting. This can often have adverse effects. 

Should symptoms persist, call your local vet for advice as soon as possible.
