Cats and Christmas trees: how to cat-proof yours, and what to give them instead

Every December, people are baffled that their cat has attacked the Christmas tree. From the cat's point of view there is nothing to be baffled about. You have carried a tree into the living room, stood it up, covered it in small swinging objects at exactly eye height and wrapped it in string. It is the single most interesting thing that has ever happened in that room.

So the question is not how to make your cat stop being a cat. It is how to make the tree less of a target, and give them somewhere better to be.

The fix most people skip: give them a taller option

Cats climb because they want height. If your Christmas tree is the tallest climbable thing in the room, it wins by default — and telling them off does not change the fact that there is nowhere else to go.

Put a cat tree somewhere with a decent view, ideally near a window, before the Christmas tree goes up rather than after. A cat that already has a favourite high perch is far less interested in a new one covered in baubles. If floor space is the problem, a floor-to-ceiling tower gets the height out of a 60 x 45 cm footprint, and wall shelves use no floor at all.

Set it up a week or two early so it is old news by the time the tree arrives. We have written separately about where to put a cat tree so your cat actually uses it, because position matters more than price.

Anchor the tree properly

A tree that falls on a cat is the serious version of this problem, and it is easily prevented.

  • Use a wide, heavy base. The flimsy stand that came with the tree is usually the weak point.
  • Tie the trunk to something fixed — a small hook in the wall, a curtain pole bracket, a radiator pipe — with fishing line or clear cord. It is invisible from a metre away and it is the single most effective thing you can do.
  • Stand it in a corner rather than open floor, so there are fewer angles to launch from.
  • Look at what is next to it. A sofa back, a sideboard or a bookshelf beside the tree is a diving board. Move the furniture, not just the tree.

The decorations that actually cause harm

Most decorations are a nuisance rather than a danger. These are the exceptions, and they matter.

  • Tinsel, ribbon and string. This is the big one. A cat that swallows a length of tinsel or ribbon can end up with what vets call a linear foreign body — the string catches at one end while the gut keeps trying to move it along, which can damage the intestine and often needs surgery. If you have a cat that chews things, do not put tinsel on the tree at all. It is not worth it.
  • Glass baubles. They break into shards that end up in paws. Keep glass to the top third of the tree, or use shatterproof ones on the lower branches.
  • Fairy light cables. A chewed cable is a burn and an electrocution risk. Run cables up the inside of the tree rather than draped on the outer branches, tape down the run to the socket, and switch them off at the wall when you go out.
  • Metal hooks. Swap them for loops of ribbon tied on — or better, short loops of garden twine, which is less tempting to chew.
  • Chocolate decorations. Chocolate is toxic to both cats and dogs. Hanging it at pet height is asking for trouble.

Plants: one of these is a genuine emergency

Lilies are the one to take seriously. Every part of a lily is toxic to cats — petals, leaves, stem, and the pollen, which they only need to brush against and then groom off their coat. It can cause fatal kidney failure, and cats have been poisoned by pollen alone. If you have a cat, do not have lilies in the house at all, and say so to anyone sending you a Christmas bouquet. If you think your cat has had any contact with a lily, ring your vet straight away. This is not a wait-and-see situation.

The others are lower risk but worth knowing:

  • Poinsettia has a worse reputation than it deserves. It causes mild mouth irritation and an upset stomach, not serious poisoning.
  • Holly and mistletoe cause vomiting and stomach upset if eaten. Keep real ones out of reach, or use artificial.
  • Christmas tree water can contain preservatives and resin, and sitting water grows bacteria. Cover the base so the cat cannot drink from it.
  • Pine needles are sharp and irritate the gut if swallowed. Vacuum them up rather than leaving them down.

If your cat is drinking unusual amounts over Christmas, incidentally, that is worth a conversation with your vet rather than putting down to the season — our guide to why cats drink more from moving water covers normal drinking behaviour.

Redirect, do not punish

Spray bottles, shouting and shutting the cat out of the room do not teach a cat to leave the tree alone. They teach the cat to do it when you are not there, and they cost you trust you will want back in January.

What does work is making the tree boring and the alternatives interesting. Give them something that satisfies the same urge: a tall sisal post with a hanging ball covers the climbing and the batting at dangly things in one object, which is essentially what the tree is offering. A cardboard scratcher near the tree gives them somewhere legitimate to dig their claws in, and kicker toys take the edge off an overexcited cat in the evening.

Two short play sessions a day through December does more for your tree than any deterrent. A cat that has hunted something is a cat that is asleep.

The first few days matter most

Novelty is the whole problem, and it fades. Put the tree up bare, leave it a day or two, then add lights, then decorations — rather than presenting the finished article all at once. Stay in the room for the first few evenings so you can redirect them calmly, and keep the bottom third of the tree plain until you see how interested they are.

If your cat is determined and you have given up, a tree in a room you can shut, or a smaller tree on a table, is a perfectly reasonable answer. Nobody is marking you on it.

Cat and Christmas tree FAQs

How do I stop my cat climbing the Christmas tree?

Give them somewhere better to climb before the tree goes up, anchor the tree to the wall, move furniture that acts as a launch pad, and keep the lower branches plain. Deterrents alone rarely work because they do not address why the cat wants height in the first place.

Is tinsel dangerous for cats?

Yes, genuinely. Swallowed tinsel or ribbon can cause a linear foreign body, which can damage the intestine and often needs surgery. If your cat chews things, leave tinsel off the tree entirely.

Are Christmas trees toxic to cats?

Pine itself is only mildly irritating, but the needles are sharp if swallowed and the water in the stand can contain preservatives and bacteria. Cover the base and sweep up needles. The far bigger plant risk at Christmas is lilies, which are potentially fatal.

Are poinsettias poisonous to cats?

Much less than their reputation suggests. They cause mild mouth irritation and stomach upset rather than serious poisoning. Lilies are the plant to genuinely worry about.

Should I get a real or artificial tree if I have a cat?

Artificial avoids the needles and the tree water, which removes two of the risks. It does not stop a cat climbing it. Anchoring and placement matter more than the type of tree.

My cat has eaten a decoration. What should I do?

Ring your vet rather than waiting to see what happens, particularly with tinsel, ribbon, string or anything with chocolate in it. Tell them what it was and roughly how much.

If the honest answer is that your cat needs their own climbing frame, our cat trees and towers run from compact two-tier models to full floor-to-ceiling towers, and scratchers and posts cover the digging-in urge. Everything under £25 is in pet gifts. Not sure what fits your room? Tell us your ceiling height and floor space and we will point you at the right one.
