The new prince of the house has made the transition from hiding under the bed at the slightest noise to throwing himself at the bedroom door in an effort to get out and explore the rest of the house.
Saber couldn't care less about the new tenant. He took one look and sneezed on Onyx, then walked away. Topper has lost a few of his marbles, and sits outside the bedroom door all day staring at it. I assume his trying to use his Jedi powers to make it disappear.
I, on the other hand, have abandon all other activities in favor of entertaining the "baby" and devising creative ways to allow Onyx and Topper to interact without getting too close to each other.
