Cats and Christmas trees have been the subject of many memes, TikToks, and even movies. In National Lampoon’s Christmas Vacation, the scene in which Aunt Bethany's cat gets electrocuted while playing with the Christmas lights prompted the famous punchline, “If that cat had nine lives, she just spent ‘em all.”

Though the quote from Cousin Eddie may make you laugh every year, you also know that the cult classic film is a work of fiction. Of course, you don’t want anything like that happening to your real-life kitty. Therefore, you'll want to prevent your cat from gnawing on the lights. Here are some reasons why cats enjoy chewing the Christmas tree lights and ways to stop it.

Why you’ll find your cat chewing the Christmas tree lights

Your fearless feline can’t comprehend cautionary tales like the one in National Lampoon’s Christmas Vacation. For your cat, the chance to chew holiday lights can feel like an extra reason to celebrate the holiday season. Cats are drawn to the tree lights because:

  • Lights look interesting, resembling a shiny new toy.
  • Cats use their mouths to explore.
  • Chewing is a way to soothe teething.
  • Playing with lights satisfies boredom.

Don’t encourage the behavior

Chewing lights is a cat behavior you’ll want to nip in the bud. In addition to electrocution risks, lights can also cause severe burns. Getting your cat to listen can be a bit of a challenge, but there are ways to curb their light-chewing tendencies.

Seeing your cat jump high into the tree can be impressive and funny at first glance, especially if they start chewing on the lights. Cats will be cats, right? Though it’s tempting to clap in awe or laugh and shake your head, these reactions will only encourage unsafe behavior.

Step 1: Don't yell. Yelling at the cat also likely won’t help the matter — it may only scare the kitty.

Step 2: Try to stop chewing before it happens. If you notice your cat eyeing the lights, redirect her to her favorite toy or lightly shake a jar with something such as dried beans in it to distract her.

Step 3: Training your cat to “come” or “leave it” can also be of benefit.

Watch wires

As intriguing as the lights look, the cat might be even more excited about the wires. In these cases, the lights are just attracting initial attention. Damaged electrical wires not only pose an electrocution risk but a fire hazard as well. Pet-proof cord protectors put a barrier between your cat’s teeth and the wire, reducing these risks.

Secure your tree

Keeping your cat out of the tree in the first place is the best way to prevent problems altogether.

Step 1: Some cats don’t like the way aluminum foil feels on their paws, nor do they particularly enjoy the crinkling sound it makes. Putting some at the base of the tree can ward off curious cats.

Step 2: Garden stones at the tree's base can serve a similar purpose as aluminum foil.

Step 3: You can put a tree skirt over the foil or stones to hide them if it’s not a look you love.

Step 4: If possible, consider putting a baby gate around the tree or even setting the tree up in a room with a door you can close when you are not home

Use scent and taste

Anti-chew sprays and deterrents can make gnawing on lights an unpleasant enough experience that your cat may think twice before landing himself on the naughty list. Some taste bad, while others don’t smell great to the cat.

Step 1: Get your vet's advice. Speak with your veterinarian before using these products to ensure there aren’t any allergens in the spray, particularly if your cat has asthma.

Step 2: Wait for your cat to be elsewhere. Don’t spray them around the cat.

Some cats just can’t seem to help themselves around Christmas decorations, particularly lights. Chewing tree lights can be a fun, soothing, and interesting experience for kitties. The problem is that it’s also extremely dangerous. Cats can get electrocuted or suffer from severe burns. What’s more, damaged cords present a fire hazard. Even if it looks funny to see your cat in your tree, it’s important to discourage this behavior. Redirect your cat with other toys or treats, and consider protecting your tree with a deterrent, aluminum foil, or garden rocks. Keeping your tree behind a baby gate or closed door and covering wires with protectors can also reduce risks.
