As I mentioned, the house is all Christmas-sy. You might recall that last Christmas, we were very worried about Pilot and the tree. To that end, we put up a low fence around the tree (that had previously served as our rabbit's outdoor pen) and he still nosed some of the lower down ornaments, but the season passed without incident. This year, he has not even seemed to notice that the tree exists. We hung some non-breakable and non-chewable ornaments down pretty far, but--nothing. The only issue we've had is that our little black cat, Stella, goes into the room at night and nibbles on branches.
We're very thankful that the rusty purple fence gets to stay outside getting rustier this holiday.
How do your pets react to trees and such?
