Unlike some cats that will bat at anything, he is relatively chill and is actually fairly selective about what he plays with. I should also note that Colonel Whiskers is a unique cat in that he doesn’t just go and play with anything and everything. I quickly picked up him and removed him from the area around the tree, and we’ve had no further issues. We’ve only had one close call, when his tail hit a branch, and startled, he turned around to see the branch wavering slightly and he did bat at it, but I honestly think he did just because it was moving when he looked at it. We began to put up all of our trees and once together, although without ornaments, Colonel Whiskers was very interested in the gleaming trees, and rubbed his face up against the branches, we knew we had to do something! Once we did the following, Colonel Whiskers has barely looked at the trees. The following is a guide of how to (mostly) cat proof your aluminum Christmas tree, but many of the notions can be applied to regular trees as well. We had both fake and real trees over the years, and the cats loved both equally. I had cats growing up, and they simply loved climbing up into the branches of our trees. Every year around Christmastime, the internet is flooded with pictures and stories of cats terrorizing Christmas trees.
