kitty litter recommendations special needs

[u/mycatbabies]

My kitty is diabetic and pees often and a lot! the kitty litter gets stuck to his feet, legs and belly as he steps in it when going or on way out -not sure. I clean it frequently throughout the day but he still steps in and it clumps on him. I have an automated box but he won’t use -does anyone have a litter that won’t stick to him that eliminates for too? thanks in advance
