So, a runt? Or just starved, neglected, finally dumped. Maybe both. In any case, you should see him now. He's such a handsome cat. So healthy and sleek, though still under weight.
He and Sassy play together now, sometimes pretty rough. But she is no longer ignoring him.
His remaining peculiarity is with running water. He loves the shower, keeps poking his head in while I'm showering. But of course, he hates to get wet. Loves to watch toilets flush, too.
And, he likes to watch TV. He's the first cat I've had that really follows the action.
