very effective subscription and it makes my life easier, no need to wear, thank you! in addition it is the only litter and God knows I've tested preque 11 years of life of my two cats who also take a long time I had tested there several years but I bought at pet has the era. then budget issue I came was to control the price first litter my usual running store but had to be changed every week because of the smell ... waste of time, and ultimately money. the price is for 1 pack of 8.4L that lasts me one month and a half by scraping the droppings every day or two days I use 1 bag per litter bin and my 2 cats used has the role of a turn 2 litters but no worries. Really great.
