My 2 have the run of the kitchen and lounge - Since putting the christmas tree up the tree has been knocked over and demolished each morning

We got Basil and Sybil (both around 5 months old) a few weeks ago and until recently they had full run of the house, including our bedroom where Basil used to sleep. After piddling on the bed one too many times though (uses litter box like a good boy all other times!), we now shut our bedroom door at night. Miss the cuddles, but was finding it hard to sleep due to monitoring his every move in case he did it again!
