Personally, I wouldn't. Bentonite clay is messy stuff, even diluted, and I couldn't guarantee hot enough temperatures to kill disease bearing organisms.
Have you looked at other options for cat litter? I used a mix of dry sawdust and dried out garden soil for years, building it up until the box was full. It partially composted in situ and there was no smell. I would then put it on piles in my young shelterbelt to let the composting finish and feed the soil/trees. Not suitable for the garden though.
