Hello, I love the litter called Swheatscoop. And yes, I had a digger for awhile but I would scruff her and tell her no and put some of her Poo in it so she learned what it was for, now , she'll only try to tip it if I don't let her out fast enough!! LOL!! I think with anything new, you have to have patience and show them what its for. I love it because it has no clay, all natural, scoopable and 1 bag will last me a month with 4 fuzzys with 4 litter pans. You can even flush it!! As far as your 2nd question, they may have not been as active because they could sense your nervousness and knew they weren't "home" and I would have done the same thing as far as bringing them with me, I couldn't part with my babies!! I'm glad their home and happy now. I hope this helps and good luck!!! Darlene & Addie & Booboo & Gracie( RIP) & Odie [Posted in FML 7239]
