Everlasting pea (Lathyrus latifolius) is a perennial flowering plant that belongs to the pea or legume family. It is native to Europe and is a popular ornamental plant, grown for its attractive flowers that come in shades of pink, purple, and white. The plant can grow up to 2 meters in height, and its flowers bloom from June until August.

If a cat ingests everlasting pea, it can lead to a condition called lathyrism. This condition is caused by the accumulation of the toxic amino acid in the body, which results in nerve damage.

If you notice any of these symptoms in your cat after it has ingested everlasting pea, you should seek veterinary attention immediately.

If you suspect that your cat has eaten everlasting pea, you should seek veterinary attention immediately. The veterinarian will examine your cat and may induce vomiting to remove any remaining plant material from its system. They may also administer medications to treat the symptoms of lathyrism.

How Can You Prevent Your Cat from Ingesting Everlasting Pea?

The best way to prevent your cat from ingesting everlasting pea is to keep the plant out of its reach. If you have the plant in your garden, make sure that your cat cannot access it. You can also train your cat to avoid plants by using deterrents or by providing them with alternative plants to nibble on, such as catnip or cat grass.

Furthermore, make sure that your cat has access to a healthy and balanced diet that meets its nutritional needs. Consult with your veterinarian to determine the best diet for your cat.
