How do you keep cats from climbing up the Christmas Tree??
We had a male who would do the same thing. We couldn’t break him of his curiosity regarding the new, climbable, thing in the house.
After the tree fell over a couple of times I decided to simply prevent the fall-overs of the tree and just let him get it out of his system.
What I did was screw the tree stand to the floor. Most stands, whether they’re the 3 legged type or the full round base will have holes in them for just that purpose. Falling Xmas trees has been a problem for a long time so the manufactures design their tree stands with that in mind.
After he climbed it a few times he simply quit doing it. Yes we had to pick up a few balls and straighten out some garland but it wasn’t a big deal.
Putting a screw(s) through your carpeting will not harm anything and it will not show after you remove the screws. The flooring under your carpet is most likely sheathing (plywood) anyway, so it’s no big deal to put a screw in it. (However, if you have carpeted over a hardwood floor you may want to think twice before screwing that tree stand down.)
I use the 1.25″ or 1.50″ sheet-rock screws for this. They are very pointed and fairly coarse threads so they pass through the carpet fibers and the backing with ease and enter the underlying sheathing quite easily. You can use most any screws, but I’ve found these to work very well.
You can get small boxes of them at Home Depot, Lowes, or any building supply center and hardware stores.
Hope this helps.
