I have noticed since Mimi’s hind legs have weakened from neuropathy as a result of the disease, she’s been “sitting” to take a pee and getting litter clumps stuck to her. I notice this because when I try to get a sample for ketone testing, she’s not in a stream anymore, she’s flat out sitting on the litter. She just had a bladder stone earlier last year and I’m worried this will give her some kind of infection eventually. anyone have any suggestions or advice on what to do? Do I need to switch her litter? She’s on Dr Elsey clumping clay litter- has been for years. Thanks!
