Well our 5 1/2 month old kitten Millie seems to have taken rather a liking to socks - thankfully she likes clean ones only!
It started one night when she pulled all the socks off the radiator and brought them to us one by one. Now she seems to have taken a liking to any that are left around the house.
I walked out of the living room to find her in the hall playing with one of my other half's rugby socks, which is actually bigger than her! Her brother doesn't seem to have mastered any new fetishes.
We have nicknamed her the sock monster!
