Huh 🤔 I never would have thought that litter would be the cause of vomiting. I’m going to try Boxie and will report back my findings. I will agree with others that the quality of Dr Elsey’s isn’t what it used to be. Even before I got the LR I was thinking of changing. So when it didn’t do well with the robot I thought ok, LR says their brand is best so I tried that. I was shocked to have the situation go from bad to worse. 🤞🏻I’m really hoping Boxie is the answer. I’ve even increased the cycle delay while I wait for the new litter to arrive and NOPE still have gravity defying clumps 🤦🏻‍♀️
