Well, I'm not sure if I'm the best person to ask about that, but here are some tips I've learned from my friend Karen. First, try placing a few aluminum foil strips or plastic bottle caps around the base of the tree. The loud crinkling sounds and reflective surfaces can scare away curious kitties. Additionally, you can create a homemade cat deterrent by mixing apple cider vinegar and water in a spray bottle and spraying it around the tree. The scent of vinegar is unpleasant for most cats and should keep them away. Finally, make sure to provide plenty of alternative entertainment and play opportunities for your cat outside of the tree
