This is the cat who, in the prime of his youth (at 2 to 3 years) managed to fall into the bathtub *twice* in the span of three minutes, because he was so fascinated with the flecks of foam moving towards the drain.

Apart from being absenst-minded, Also, he gets startled easily, and fights with his brother when he's stressed.
So many occasions for accidents...

Chubby Cat is more coordinated, and seems to have better situational awareness.
