A company has sent me 2 bags of clumping litter (marked sample A & sample B) to try out and a questionair. Now me not being a rude person needs to full in the questionnaire honestly. I cannot think of any words to describe how awful both samples are, really they are almost the same bit one slightly darker than the other. On the instructions it says don't flush down the loo, that may be because once wet it sets like cement and sticks, talk about chisel off the bottom of the tray. The smell after one wee you could smell it in the lounge (the tray is in the kitchen). The tracking is far worse than the wood pellets.
If anyone purchased litter for the first time and used that, it would certainly put them off having a litter tray in the house for life.
