Ritzy is so quiet in the litterbox (except for flinging the litter around), so when she once began crying during and after peeing, I KNEW it wasn't right, even though she acted otherwise healthy...

Sure enough - to the vet we went immediately - a urinary tract infection, which left untreated can be disastrous.

Get kitty to the vet pronto! Going to the bathroom shouldn't hurt - this is true of humans AND kitties!
