After 6weeks later, I am confidence to say, the training is done! I might leave this green tray for her. It is easy to seat for her and it does not have litter for me, so win win situation. I am so happy the litter drops gone forever! Disgusting litter odder gone forever! my expensive vet bill gone down! My cleaning house came back to normal! yay! I am so thanks to my cat spice, done so well, and did not had any accident for this whole training. I am the lucky one!
