Are Bonsai Trees Safe for Cats?

Bonsai Trees are not safe for cats. Some species of Bonsai trees can be specifically fatal to cats if they are ingested in large amounts.

Bonsai trees can be excellent plants to add to your collection if you have a green thumb, but some Bonsai trees may pose some risks to your cat’s safety and health.

Read on to discover why Bonsai trees are unsafe and what types of trees to avoid if you have cats. We will discuss some Bonsai trees that may be safe for cats and what symptoms to look for in cases of Bonsai tree ingestion. 

What Makes Most Bonsai Trees Unsafe for Cats?

Cycasin is a toxic agent found in several species of Bonsai tree that can be harmful to cats, and in some cases, fatal. Cycasin is found in all parts of the Bonsai tree, but seeds and buds of these trees are the main perpetrators of the plant that cause fatal reactions.

What Happens If My Cat Ingests Part of a Bonsai Tree?

Depending on the species of Bonsai tree you have, if ingested, your cat could experience anything including:

  • Minor irritation on the skin
  • Upset stomach
  • Liver failure. 

It is essential to do your research and keep any potentially fatal Bonsai trees away from your cats. 

Toxins in Bonsai Trees

Cycasin, the toxic agent found in some Bonsai trees, will damage the tissues in cells of the liver and release toxins into the bloodstream. Within 15 minutes, your cat could experience liver damage or failure if it ingests part of a Bonsai tree that contains Cycasin. 

The seeds and buds of a plant can contain higher amounts of the toxin, Cycasin and can be naturally more harmful to cats. The leaves and stems of several Bonsai variations contain just traces of Cycasin but can still bring about mild symptoms of Cycasin poisoning. 

Dangerous Alkaloids Found in Bonsai Trees

Alkaloids are organic plant compounds that have a physiological reaction on humans and animals. Alkaloids can produce mild to fatal responses and are commonly found in Bonsai trees and plants. 

  • Buxine is an alkaloid found in some Bonsai variations that can cause vomiting, nausea, and respiratory failure in cats, humans, and livestock. 
  • Boxwoods contain two additional toxic alkaloids:
    • Cyclobuxine
    • Clycloprotobuxine

These alkaloids found in many species of Bonsai tree are the fatal components that will harm your cat if they ingest any part of a Bonsai plant, but specifically the seeds and buds. Consuming these alkaloids will cause vomiting and diarrhea, among other, more severe symptoms.
