What is it with Cats and Christmas trees? (and how to keep them safe)

If you share your home with a cat, you already know: when the tree goes up, the holiday hijinks begin. It’s as if your cat takes one look and declares, “This? This is perfect. I will climb it at once.”

But behind the comedy is some very real feline behavior—and a few important holiday safety tips every pet parent should know.

Why Cats Love Christmas Trees

1. It’s an Indoor Forest Playground

Cats are natural climbers, and a tall, branchy tree is basically an indoor forest dropped directly into their favorite room. The new height, new smells, and new textures are irresistible.

2. Ornaments = Moving Target Practice

Shiny, dangly ornaments are designed to catch the light… and apparently designed to catch paws, too. They activate hunting instincts, especially anything that sparkles or sways.

3. It Changes the Territory

Cats thrive on routine. A giant tree alters the scent map, the layout, and the energy of the room. Curiosity—and sometimes a dramatic climb—is their way of investigating and taking control.

4. It’s New, Big, and Breaks the Rules

Anything new becomes the center of a cat’s universe. A bright, tall, glittering invader? That’s a full-blown feline research project.

Holiday Hazards to Watch

The antics are adorable… but safety matters. Here’s what to keep in mind:

Tree Water

Cats love “mystery water bowls.” But tree stand water can contain pine sap, fertilizers, stagnant bacteria, and mold—all of which can cause vomiting or GI upset. Cover the reservoir securely or block access.

Tinsel and Garlands

Pretty but dangerous. If swallowed, tinsel, tinsel garlands, or foil-like garland and decorations can cause digestive problems or intestinal blockages. (Please see educational information at the end of this blog on what to do if your cat has tinsel or string in their mouth.)

Fragile Ornaments

Glass ornaments can break with one swat, putting paws and noses at risk. Use shatter-proof ornaments on lower branches.

Lights & Cords

Chewing or pawing can cause burns or electric shock. Secure wires and use cord protectors.

Tree Stability

A climbing cat can topple an unsecured tree. Anchor your tree to a wall or ceiling for extra stability.

Making the Holidays Happier (and Safer)

• Give your cat a comfy, safe spot to supervise the decorating (because they will supervise)

• Keep breakable or irresistible ornaments higher on the tree

• Use sturdy hooks and firmly secure ornaments

• Add a tree skirt or decorative barrier to block access to the tree stand water

• Keep cords tidy and out of reach

  
  

A few simple steps can help your cat enjoy the season without turning your tree into an action scene.

And let’s be honest—would it even feel like the holidays without the occasional 2 AM ornament chase?

Educational Note:

If You Ever See Tinsel or String Hanging From Your Cat’s Mouth

Do not pull it.

String, tinsel, and linear objects can catch on the tongue or wrap around the intestines, and pulling can make things much worse. Instead:

1. Keep your cat calm and prevent them from swallowing more - Gently confine them to a quiet room.

2. Do not try to remove the material yourself - Even if it looks small, you can’t see what’s happening internally.

3. Call a veterinarian or pet urgent care facility right away - They’ll guide you on the next steps based on your cat’s condition.

4. If your cat is drooling, gagging, vomiting, or pawing at their mouth, seek immediate veterinary care.

A quick call—and avoiding the urge to tug—can make a huge difference.
