Thank you. I didn't see that thread first. It was educational about the Miralax and the pumpkin.

Questions remaining: Is 2/3 of a can of food every day sufficient for Tiger? Should kitty treats be eliminated along with the free range dry food?

Question possibly answered: Why does Tiger urinate on the cookie sheet, but defecate beside it? The suggestion was made that maybe that's her way of telling me she's constipated.

And for the record, those with older kitties who can't climb into a regular box, the cookie sheet seems to be a good idea.
