Query: worked on artificial christmas tree!

My cats want to chew on anything plastic, including the christmas tree. We bought this and sprayed it on the tree as we were assembling it and it worked well! they would nible, move to a new spot, nibble, move etc until they finally decided that the entire tree must taste like this and they gave up! Over the holidays, we did have to re-spray around the bottome maybe once a week or so, but that was a small price to pay.We also used it on speaker wires that one of the boys had chewed through 3 times and he hasn't touched it since.
