We have a found a great way to get Loki into the house, and to have him do some 'lets tired him out' activity. An inexpensive cat toy we got at Cat Haven for $2. Two floaty feathers, attached to a small rod, dangling by fishing line. Unfortunately, he likes it so much, it's very bedraggled and kinda mauled.
So, Aikidomayland and I went to Spotlight and picked up a small bag of masquerade feathers, some smallish downy ostrich or emu feathers (not too sure which, as they have been bleached and dyed) and with some dental floss, and an old rod with with the cat toy long gone, have made him a new one. We have enough feathers to make several more as needed.
Also took advantage of the post holiday sales and picked up a very nice wreath to use next year. Didn't get a tree.. not with the two nutjobs.
