Last night I watched Thatch and Annabelle play. There was some "tag-you're it"; then they wrestled till she pinned Thatch down and he squealed, and she ran away and he trotted after her; then she sat in the cat tree and he sat on a lower level and tried to catch and bite her tail. He's getting awfully good at jumping, although he tried to jump twice onto the chair where she lay and missed both times, falling to the floor in a loud splat. The third time he made it.
