BCSnob - I like the toy searching. I am considering doing some tracking with him once he's older. Just want to stay away from him having to "get through" things to get the object as a JRT is bred to dig.
Speaking of finding toys, one time I was sitting in the living room on the phone and Looney2 (cat) came down the stairs dragging a throw blanket behind him. He dragged it off the bed, into the hall, down the stairs, through the living room and into the dining room before abandoning it. He was about 6 months at the time. A few days later, he tried to drag the winter comforter off the bed.
I couldn't figure out why until I discovered that at night while I slept, he would bring one of his worms (elastic hair bands) onto the bed for me to throw for him and it would get caught up in the blankets. He was trying to get the worms out of the blankets.
Now, he corrals his worms in the bathtubs.
