Calcium oxalate crystals

Shame does not carry a grudge against your plant, as more than 215 families of plants produce the same poison, calcium oxalate crystals. The primary function of these crystals is to regulate your plant’s calcium levels and prevent herbivory, protecting them from being eaten by predators.

According to a Botanical Study in the Sevil Tütüncü Konyar journal in 2014, these crystals you see in the seeds, stems, leaves, roots, and flowers.

You might have even consumed some of it when eating certain plants, even without realizing it. For example, maybe you have nibbled on a wood sorrel genus looking like the clover plant, and it has a tangy taste. Well, Oxalis is known to contain oxalic acid. You find it in spinach, kale, swiss chard, and turning greens.

The fact is that you can consume a low concentration of it regularly. But if you have digestive or kidney problems, then you need to change your diet. The substance is even used in the industrial market to rinse laundries to remove rust or a vehicle radiator to remove scale.

The plant needs the crystals to protect them from being eaten by animals. Interestingly enough, it even forms in the human body how calcium oxalate is the constituent creating kidney stones that are an excruciating pain when they move through the bladder.

Symptoms Your Cat is Poisoned

According to the Animal Society For The Prevention of Cruelty to Animals, there are common signs that you’ll observe to indicate that your cats have been consuming parts of your peace lily or other commonly grown species:

  • First, you will notice your excessive drooling at the mouth.
  • Next, your cat will have oral pain curling around on the ground.
  • Next, the cat will be pawing at the mouth.
  • Finally, your pet might start to vomit.
  • Lastly, your pet may have a decreased appetite with difficulty swallowing food.

All of these symptoms occur after your animal chews on the plant. The reason this happens is that the crystals work like microscopic spears. It penetrates through the cat’s mouth tissue from the gums and tongue.

Then it works its way down the esophagus, causing a burning sensation—shame who could blame your pet for yowling in pain under these circumstances. Your poor animal will even meow with different tones as the discomfort becomes intense, starting to drool.

In most cases, if your cats have eaten some of the peace lilies, the case of an airway swelling up, making it difficult for your cat to breath, is rare.
