I would like to know your thoughts about cats and Christmas trees, both real and artificial. I am very concerned about my cat, Sonny, ingesting some of the tree.


Christmas trees and decorations are a yearly challenge. Live, cut Christmas trees can be deadly for cats. Pine needles can be ingested and puncture intestines, and pine is highly toxic to cats, potentially causing liver damage and death. Additionally, the water that cut trees are placed into is toxic. It usually contains pine resin, preservatives and fire retardants.

Fire retardants are sprayed on artificial and live trees and pose a potential danger. A 2007 study published by the Environmental Protection Agency linked fire retardants to thyroid disease in cats and possibly humans.

An artificial tree is generally safer than a live one. However, if eaten by a cat, it can cause intestinal blockage. A bitter apple spray can be sprayed on the tree as a deterrent before trimming it. The spray sometimes stops cats from exploring or chewing on a tree.

It is important to secure the tree so that the cat is unable to knock it over. Some people secure their trees from the ceiling or rig up a way of tying the tree to a nearby wall. Recently, I saw a unique solution to the tree dilemma. The fully trimmed tree was hanging upside down from the ceiling. It was both beautiful and at the same time impossible for the cat to reach.

Christmas decorations also can be deadly to cats. Cats like to play with tinsel and if swallowed, it can cut a cat internally or form an intestinal blockage. Ornaments must be tied securely to the tree, so that an exuberant cat can’t dislodge them. Not trimming the lower branches of the artificial tree can help decrease a cat’s natural curiosity about ornaments.  It’s important to be aware of the potential hazards of Christmas trees and their decorations. To be on the safe side, close the door so that your cat doesn’t have access to the tree unless the cat is supervised.

  • I have just discovered that electrifying my artifical tree has detered my 3 rescue cats from exploring after the third shock.

  • I have an artificial tree which I secure with clear duct tape on the stand. It works great and the tape comes right off the floor when the tree comes down. I also have a cat “no scratch spray” I use. This system works real well for my three cats.

  • I have a cat that try’s to eat the fake tree…she started puking last night and has been today. I am worried its because of the tree. Has anyone else had this problem?
