I was thinking about Piff this morning, wondering how he was doing, and I am so glad to hear that he has bounced back! I always wanted my kitties to sit on my shoulder but they never got into it, and I am jealous.
My cats love anything plastic that they can carry around in their mouths (think shower curtain rings, little thread spools (with no thread left), ninja-cat stars (I don't remember where I got them but they were for cats but looked like throwing stars ... I'll try & find out what brand they are) etc).
