Is a Bonsai Tree Safe for Cats?

Cats love to nibble on plants found both indoors and outdoors. Strays will do this while living outdoors to meet nutrient requirements in their diets. 

As a cat owner, you most likely think very seriously before bringing houseplants into your home. Maybe you already have a beautiful bonsai tree and noticed that your favorite feline is very interested in it, but is it a toxic tree to cats?

Yes, some bonsai tree species are poisonous to felines, but there are others that are not toxic to cats. Bonsai trees and cats can co-exist, but you’ll need to understand some basics to protect both your miniature tree and your favorite feline. Some plants are toxic to cats as well as to other pets if bonsai leaves are ingested. 

The first thing to consider is that “bonsai” is not a specific plant species, but refers to the grooming style used when growing a plant, usually a small tree.

Numerous plants can be cultivated in the Bonsai style by being grown in a container. They are generally tree species or plants with woody stems and branches. There are also bonsai tree species best for indoors and others better for outdoors. 

The bonsai concept is to grow and cultivate the tree in a small container so that it maintains a miniature size and the appearance of a tiny tree.

Some of the more well-known tree species that are cultivated as bonsais include:

  • Cedar
  • Cherry Tree
  • Cypress
  • Juniper
  • Maple
  • Pine

Depending on the tree species that you cultivate, your bonsai may or may not be harmful to your cat. As a pet owner, you need to know which species are toxic. As a bonsai gardener, you need to know how to protect your beautiful tree from a munching feline.

Many cats will ignore plants, so co-existence with a bonsai will not be a problem, but there are no guarantees. Some trees may be harmless if ingested in small amounts. However, if the pet chows down on your bonsai and in the process, ingest large quantities, they can become toxic.

Let’s take a look at the best and worst bonsai tree species, and then look at common symptoms from poisoning in case of ingestion.
