Today is my schedule to replace cat litter that has been used for too long, it still looks good and can still absorb kitten urine. But this was too old so I threw it away and replaced it with a new one, this is for their convenience when urinating.☺️ Now there is only 40% of cat litter left from 20KG, maybe a few more kilos left, but it can still replace the dirty sand later, so I can save money again.☺️
