[[ comes to something when you can tell who is using the covered litter
box just by the way the litter is being scraped, in the same way I can
tell who is jumping onto the bed at night without me looking and I can
tell who is going up and down the stairs or eating out of the bowl! I
obviously know my cats too well! ;o) ]]

Don't feel bad. When Melody and Harmony had collars made by different
manufacturers, I used to be able to tell the difference between the sound
of the bells.

I can't do that with Captain and Stanley at the moment, as they've both
got the same kind of collar and the bells sound alike.

But I know how it is, being able to tell one cat from the other from some
interestingly subtle clues.

Hehehehe... I can tell mine apart by touch and by sound. :)

Heh. I can do that too. I don't have a covered litterbox, otherwise it's
the same. I know which cat is there just by the sound of the scratching.
Of course, you have more cats to recognize than I do.
