The kittens are about 4 months old. I was sitting with them on the sofa, cuddling and playing. Well, when I was busy with one, the other two lay down by my sides and stretch their paws inside my pockets. They were able to get the tissues and the house keys. The boy, Kuro, even kicked the keys down to the floor. Hope this is not going to be a habit. Or I'll make sure to wear clothes without pockets when I am with them.
