Our sustainable cat litter
Why it works so efficiently
PurrStainable forms tight, lightweight clumps, so you only remove what’s been used. Traditional wood pellets break down into sawdust, meaning you throw away far more material each time you clean the tray.
Because the litter stays fresher for longer, you top up less often and empty the tray less frequently. This is why rescues switching from wood pellets consistently report major reductions in usage and waste.
