Ahhh right! I know it sounded silly, but with Katie being my first cat and even though i've had her two years, i'm still learning!
I'll stir it up - thanks for the tip!
Katie finds it ok, but her scratching in the tray has definately lessened, so maybe she doesn't find it as comfortable... it certainly does make a racket when she's in there!
Are there any litters that you've found that encourage digging? Sounds silly, but she doesn't tend to bury her poos which contributes to smells, but I don't mind really!
