Has anyone used So Phresh Pine Pellet litter? I used Feline Pine for several years with my former cats (we all loved it) but have thus far been using only clumping clay litters for my new senior cat Bochy as she is still recovering from several bouts of diarrhea. I'd like to go back to a pine pellet once she's stable and have heard that the product integrity of Feline Pine has noticeably declined in recent years. So Phresh is a Petco brand, readily available locally, and is reasonably priced but I haven't found much in the way of reviews for the product. Any feedback would be welcome.
