In the interest of conserving memory, consider this:
Randomly distribute the NKIs and kitten, then check each cell to see if 
they have more than n "live" partners.  If there are too many, kill random 
partners until we're at n.  Cells that die would be distributed again, 
then check again.  Repeat until no more cell deaths.  This would still 
allow a cell to be locked up in a large area, but I've noticed that such 
an event is exceedingly rare.  It's more common for a single live cell to 
have all its partners live.  Even then, when I run a game of 589 (maximum 
for Inform), I only rarely find a landlocked cell.

Any other ideas?
