Ripley was my only cat for 10 years before the flood gate of kitties opened. Anyway, he usually only peed a couple of times a day but it would be huge when he did go. The clumping litter would be softball size but of course in his healthier days he weighed 18-20 pounds.

I don't think I would worry too much if she is eating, drinking and acting normal.

You'll have to come over some time and meet "The Gang". Maybe you'd want to take Moxie and Decker home with you. I know Miss Squeak would never go for that.
