Last year, for Christmas, the kittehs got home-made catnip toys (a felt mouse I sewed and filled with catnip and cotton).
Being kittehs, they took their toys and put them in inaccessible places...El Gato usually puts hers underneath a rug and lays on top of the rug pretending she doesn't know how to get to it. La Doof Kitton prefers to put his in boxes or bags and lay outside them, reaching one arm all the way in to tease the toy.
Apparently, last Christmas, La Doof Kitton put his toy in one of the gift bags I had out to transport gifts from here to there...because when I went to fill it this year, I found his catnip mouse, a pom pom and part of a ribbon. They've been packed up for the last year--maybe he won't hide them quite as well THIS year.
(he's off playing with them right now)
