If you celebrate Christmas, there’s a good chance you put up some kind of Christmas tree. If you read this blog, there’s a good chance you have at least one cat or are thinking about getting one. So if you celebrate Christmas and read this blog, then you probably have reason to keep a cat out of a Christmas tree. Me too, my friend. The two cats we had growing up actually showed very little interest in the Christmas tree, except as a new thing to sleep under. But in recent years, I have lived with cats that had a lot more holiday cheer, shall we say.

So this article is for Sven, my roommate’s cat who thought a two-foot plastic tree would somehow stand up to 10+ pounds of tomcat flinging himself into its branches. And for Joon, whose teeth marks are forever left in my shiny foil Christmas present ornament. This will be her first Christmas in a house with a Christmas tree that’s actually large enough for a cat to climb, and I am panicking more than a little. But my research says all hope is not lost.

Choose Your Tree Wisely

I have never once had a live Christmas tree. I was probably eight years old before I found out that was a thing people did. Now I know that for many people, the live tree is a big part of their holiday tradition. And the first people to put up Christmas trees certainly weren’t using plastic ones, so tradition really is on your side if that’s your preference. However, live trees are much more attractive to cats than artificial ones.

Climbing is hardwired into the feline brain, and one of the most readily accessible climbing surfaces in nature is trees (1, 2, 3). In addition to climbing trees to hide, hunt, and survey their domain, cats also use trees to mark territory (1, 2). Marking can include rubbing and scratching or really quite unpleasant urine and fecal scent deposits. Artificial trees can look similar to real trees, but they don’t smell like them. Scent is very important to cats–hence the marking–so when you bring in a real, live tree, they know it’s a tree (2, 3). And their feline mind has very different ideas about what a tree in the living room is for than you do.

If it’s really important to you to have a live tree, it can be done, but it’s easier (and often safer) to have an artificial one. Whichever flavor of tree you choose, keep in mind that smaller trees are less likely to become kitty jungle gyms (2). Plus, if your cat does climb the tree and manage to knock it over, the smaller the tree is, the less likely your cat is to get injured in the fall (4). Slimmer trees also make less appealing targets, so consider a pencil tree if you’re going artificial or a live tree with a similar profile (5).

Location, Location, Location

Once you have your tree picked out, you need to set it up. Depending upon the tree, that can be an ordeal in itself, but with a cat extra care needs to be taken. First of all, make sure that you have a heavy-duty base to secure your tree with (1, 2, 4-6). The hope is that the cat won’t climb the tree at all, but you want to do your best to keep the tree from toppling if they do.

Next, look for a place where there would be plenty of open space around the tree: no furniture, cat trees, or other launching pads your cat might jump into the tree from (1, 2, 4-6). Ideally, the amount of empty space around the tree will be equal to the height of the tree (2). So a six foot tree would have a furniture-free zone extending six feet from it in all directions.

Of course, having that much free space around the tree isn’t always practical. Fortunately, you can work around the need for so much space in a number of ways. We’ll get to the more complicated ones later. The simplest ways are to 1) have a shorter and/or slimmer tree that doesn’t need such a big zone around it, or 2) put the tree in a corner (6). That completely eliminates two directions from which a cat could come flying. It’s also safer for your cat–and your decorations–because it eliminates two directions in which the tree could fall, too.

If your home is amenable to it, it’s a good idea to secure the Christmas tree to a wall or the ceiling. Screw an eyebolt into the wall or ceiling and tie the tree to it with clear fishing line. It’s a nearly invisible fix that might prevent a disaster. Just make sure your cat doesn’t get ahold of the fishing line and decide to eat it! (1-3, 5, 6)

If you really want to keep the cat out of the Christmas tree completely, you may want to put the tree in a room that you can close off and restrict the cat’s access to (1, 7). Before you decide to shove your beautiful, festive tree of holiday cheer into a back room somewhere, though, wait until we’ve gone over all the options. There are lots of tricks you can try yet.

Ornaments Hung by the Greenery with Care

Decorating the tree is one of my favorite Christmas traditions. I love the beauty of the ornaments and remembering the history of each one as we go through them. Unfortunately, to cats, ornaments look an awful lot like toys. To avoid broken ornaments and possibly trips to the vet, we have to be careful about how we decorate our trees.

You may want to start decorating the second you get the tree put up. I know I do. But hold off for a while. If you leave the tree bare for a few days, it gives your cat a chance to investigate it and hopefully get bored of it before you start hanging any tempting baubles (4).

When it is time to decorate, first things first: if you decorate with tinsel, don’t. This is one thing that is non-negotiable. I know, tinsel is shiny and awesome, but cats think so, too. And they respond to shiny, awesome things very differently than we do. Cats infamously like to eat tinsel, and when they do the tinsel can choke them or get caught in their digestive systems (2, 4-6, 8). These are life-threatening emergencies. The digestive blockages caused by tinsel usually require surgery to repair. So, no tinsel.

Garlands may also be a chewing hazard, but it depends upon what they’re made of. Food garlands might seem safe, but some human foods are toxic to cats, not to mention that they tempt your pets to get into the tree (6). Anything tinsel-like has the same risks as tinsel. Paper garlands can be a good idea (8). They aren’t very attractive to cats, and if kitty does nibble them, it’s no big deal. Wood also doesn’t grab a cat’s attention the way shiny things do (3, 5).

Now, for the main event–the ornaments. Perhaps the simplest thing to do is not decorate the bottom of the tree at all (2, 4-6). How much of the tree you leave plain is up to you and the reach of your cat. Pet Health Network suggests not decorating the bottom fifth (2). Alternatively, decorate only with unbreakable ornaments at the bottom–wood, plastic, felt, burlap, etc. (5). That may still be too tempting and get your cat too interested in the tree, though. You can always try and see how it goes, if you’re feeling brave.

It’s best to only decorate with unbreakable ornaments, really. They’re typically less shiny, so they don’t attract cats as much (3, 5). And those fragile glass ornaments, while beautiful and often sentimental, can be very dangerous for your cat if they break them (1, 6). They might ingest small pieces or cut themselves on the sharp, broken edges (1, 6). And even if no one gets hurt, who likes broken ornaments? No one, that’s who. But most of us have some fragile favorites that we like to see on the tree every year. So make sure to put them toward the very top of the tree and secure them well. In fact, secure all your ornaments well.

The more ornaments sway, the more enticing they will be (3). Metal ornament hooks can hurt your cat’s paws if swatted or stepped on, and they aren’t very secure anyway (4, 5). Instead of hooks, consider tying your ornaments to the branches with twist ties, wire, or twine (2-6, 8).

The Art of Deterrence

Now we get to the more creative approaches. If you just can’t keep your cat out of the Christmas tree in any of the above ways, try the following. Remember, however, that wherever you say “no,” you must also provide a “yes” (3). If the only climbing/scratching/perching surface in the living room is the Christmas tree, there may be no amount of deterrence that will keep your cat from trying to get into it. The Christmas tree is usually in a socially significant area of the house, so your cat will want to hang out in that area with you (3). Therefore, make sure that you have a tall, quality cat tree in the room with the Christmas tree as an appropriate alternative to the tree itself (3). Just don’t put it too close to the tree, or your cat will be tempted to jump between the two (3)!

Started from the Bottom

If your cat is climbing the Christmas tree from the base, there are several ways you can discourage them from this point of entry. Wrap the bottom of the tree trunk with aluminum foil (2, 4, 5). Cats usually don’t like the sensation or sound of foil. A circle of foil under the tree skirt may also work (4, 7).

A more heavy-duty solution for the problem is the Christmas Tree Defender, a circular grate made of green plastic that clips around your tree. It can also be used for potted plants year-round. It is treated with a flame retardant, though, so it may not be suitable if you have a cat that likes to chew hard plastics.

Trees Are Not for Eating

Speaking of chewing, Christmas trees and their strings of lights can be tempting targets for chewers. Cats are known for investigating new and interesting things with their mouths, but when it comes to Christmas decorations, this is not just destructive but very dangerous. Pine needles are sharp and toxic to cats (3, 4, 6). Artificial needles can be dangerous if eaten, too, as plastic doesn’t really digest (1). Then there’s the lights. Some cats just can’t resist chewing on cords, but if they reach live wires within, burns on their mouths are a best-case scenario.

What to do? For the lights, apply a pet-safe bitter spray or cream to them before you string them on the tree (2, 3, 5, 6). If using a spray, it’s best to spray a cloth and then wipe the cords with the cloth (5). Make sure to wear gloves! If you have a pre-lit tree, this will obviously be a rather difficult endeavor. Just do your best and tuck away any dangling wires once you’ve coated them. You can also spray the whole tree with bitter spray, which works for cats that want to chew the branches (6).

Unplug the lights when not in use to minimize the chances that the wires will be live if the cat bites into them. It’s also a good idea to use a cord cover on the unlighted length between tree and wall socket so that the cat is unlikely to chew through to the wires at all (1, 3-6, 8).

Prevention is Scent-sational

There are certain smells that cats do not like. There are exceptions to almost every rule, but most likely your cat won’t be a fan of citrus, citronella, menthol, and apple cider vinegar (1, 3-5, 8). You can buy cat repellant, usually citrus-based sprays to spritz the Christmas tree with (1, 5), or you can use a variety of homemade solutions.

Cat behaviorist Jackson Galaxy suggests putting citrus zest, whatever kind strikes your fancy, into plastic bags, poking a few holes in the top, twisting them up, and hanging them inside the tree (3). He says that from a distance nobody will think anything of it (3). I trust Jackson Galaxy to the moon and back when it comes to cats, but I do wonder about his aesthetic sensibilities. You could maybe do the same with cheap plastic Christmas balls with holes poked in the top, but I haven’t tried it. I might, though, so watch this space. Other possibilities include:

• Placing lemon or orange peels around the base of the tree (4, 8)
• Including orange slices or strips of orange peel in the tree decorations (5)
• Spray pinecones with apple cider vinegar and place them at the base of the tree (8); if using pinecones from outside, bake them in the oven at at low heat to kill any bugs first
• Mix a little citronella oil into a spray bottle of water and spritz the tree with it (8)

Not-So-Holy Water

One of the big problems with cats and live trees is that cats want to drink the tree water. This isn’t just weird. It’s unsafe. The water may contain pine sap, fire retardants, pesticides, and fertilizers, all of which are toxic to your cat (1, 2, 5, 6, 8). Not adding anything to the water yourself, i.e. Aspirin, can prevent further toxicity, but it’s best to keep the cat out of it any way you can. Some tree stands include a cover for the water bowl, so if you can find a sturdy stand with a cat-proof cover, you’re in luck (1, 6)! But if not, aluminum foil or plastic wrap can be your friend here just like on the tree trunk (1, 2, 8). Netting or Sticky Paws for Plants, a kind of double-sided tape for deterring cats, are other good choices (6).
