I would not advise dumping used kitty litter in the compost heap.  I don't
remember the details, but there is some sort of disease that can be
transmitted from cats to humans via cat feces.  I understand that pregnant
women are particularly at risk, and should not handle catboxes at all.
I don't know whether the disease organism would survive a trip through
the compost heap, but why risk it?  You'll also get odors and flies and
a generally unpleasant mess, and won't be adding that much to your compost.
I would think that the fact that cats are carnivorous would imply that their
feces are substantially different in composition than those manures that are
generally added to compost:  cow, horse, rabbit, chicken, etc.
