I don't have a cat right now, but I have about 12 of them in the past and they loved to hang on Christmas trees..making my mom so mad. The other day I was at a relative's place and their cat was all over the tree. I thought that the lady of the house allowed it until she screamed and ran as if her house was on fire.. the poor kitty was all scared and in his attempt to run away got completely entangled in the garland.. It was such a funny sight to see.. Kitty wrapped in garland.
The lady had a neat squirt can which she used when any of her other cats came near the tree and they seemed to leave it alone. She was also told me that her kitty ate up the garlands as well.
