Are Cypress Trees Poisonous to Cats?


Cypress trees are beautiful and popular additions to many gardens and landscapes. However, if you have a cat, it’s important to consider the potential dangers that certain plants may pose to their health. One common question that cat owners often ask is whether cypress trees are poisonous to cats. In this article, we’ll explore the topic and provide you with the information you need to keep your feline friend safe around cypress trees.

Types of Cypress Trees

Before diving into their potential toxicity, it’s important to understand that “cypress” is a broad term that encompasses various species of trees. Some common types of cypress trees include:

  • Italian Cypress (Cupressus sempervirens): Known for their tall, slender shape, Italian cypress trees are commonly found in Mediterranean regions.
  • Bald Cypress (Taxodium distichum): These trees are known for their distinctive “knees” that protrude from their roots and are often found in wetland areas.
  • Arizona Cypress (Cupressus arizonica): Native to the southwestern United States, Arizona cypress trees are known for their blue-green foliage and drought tolerance.

Potential Risks for Cats

While cypress trees are not generally considered highly toxic to cats, there are some potential risks associated with them:

1. Essential Oils:

Certain species of cypress trees, such as the Italian cypress, contain essential oils that can cause gastrointestinal irritation if ingested by cats. Ingesting parts of the tree, such as the needles, small branches, or cones, may lead to symptoms like vomiting, diarrhea, and abdominal discomfort.

2. Allergies:

Cats, like humans, can develop allergies to various plants, including cypress trees. If your cat comes into contact with cypress tree pollen, they may experience allergic reactions such as sneezing, coughing, itching, or watery eyes. These symptoms are more common during the tree’s pollination season.

3. Physical Injuries:

Some cypress trees, such as the bald cypress, have root structures called “knees” that protrude above the ground. These knees can pose a tripping hazard to cats, potentially leading to injuries like cuts, scrapes, or sprains if they stumble or jump onto them.

2. Create Barriers:

If you have cypress trees in your garden or yard, consider using barriers, such as fences or netting, to restrict your cat’s access to those areas. This can help prevent direct contact with the trees and minimize the risk of ingestion or injuries from tree knees.

3. Regularly Clean Pollen:

During pollen season, regularly clean your cat’s fur and paws to remove any pollen that may have collected on them.

This can reduce the risk of allergies or potential ingestion if your cat grooms themselves.
