I’m really impressed so far, only been using it for 3 days but so far so good…only ‘issue’ was one of my girls started sneezing when I first put it in litter, then seemed reluctant to use it initially…saying that, they do seem slow to get onto the litter box , as in both maybe a little curious? I put this down to it being totally new for them? I love the fact it doesn’t smell, it doesn’t clump and they have both been using it as they would their previous one, had no other issues so far.
