[Cob] How warm must it be to work?

[Amanda Peck]

It's been a long time since I've used that kind of kitty litter--the sawdust 
types are much nicer, both for the cats and for me--but it doesn't separate 
into slip if the bottom layers stay in liquid too long.  So I'd guess it 
either has some gypsum in it, or else is a very low-fired clay.

What is the deal with kitty litter. Is it clay or not?
If it is could you mix it with paperpulp and  make some kind of adobe?
