I have an elderly cat that has diabetes and urinates frequently...he has been having trouble keeping his feet clean during the process and sometimes ends up with clumps stuck to his feet. It is the self-clumping litter. I would prefer not to switch to reg. litter if possible because I have another cat that shares this box and of course his frequent urination means I am already constanstly scopping it (atleast once a day). But I know it is uncomfortable for him when I try to clean it (he is long-haired, with fur in-between his toes). Any other suggestions would be greatly appreciated.
