So far, so good this year - we only had a little one in a pot last year, up on a chest - he did have a sniff but didn't bother too much. This year we have a 5 foot one, but up on a table in the corner by the sofa. Again a few sniffs from the sofa, and he's nosed a bauble and a bow once or twice, but, apart from that he doesn't seem bothered.
