The Cat and the Socks

We have three cats and I love two of them dearly. The other one belongs to Ga'Hoole Girl. She can be a very nice cat, but she has a bad habit of attacking the other two cats. So, she's already on my bad side most of the time. She has developed a new annoying habit, though. She takes dark socks and carries them around the house. She will take them out of the clean or dirty laundry baskets, off the table, or from whereevery they are around the house. Then, she drops them somewhere else in the house. There is no rhyme or reason to it. She's not hoarding. She doesn't play with them. She just carries them around. And, she only does it to dark socks, not white socks. So, I'm now training the rest of the family to get the clothes put away quickly so Sophie doesn't carry the socks off. Arghh.
