Thanks! Pippin and Merry are (we believe) twins. They are both tuxedo cats and it is very hard to tell them apart at first glance. It's getting easier now that he is a bit larger than her.

The funny thing is, I always thought he was dumb as a rock, but he fooled me! And we didn't reward him with treats to get him to fetch, either. Only praise and much petting. He just loves to play with us, I suppose.
