Lacey, I know a few people who have tried the Crystal litter and some of the cats were okay with it and others were not.
I agree with the others in trying different types of litter and hopefully one will be to Mowgli's liking.
I'm so glad too that you are not giving up on this little sweetpea.

Group hug for you Lacey for support.

Praying that Mowgli goes, where no man has gone before, in the litterbox. (Sorry, couldn't resist. I'm in one of my silly moods tonight.)

Mind you, maybe there have been some men who have gone there before. Who knows.
