In addition to the papers suggested by Todd Wilson, here is a recent paper 
specifically about epis in CAT:
Bernarczyk, M. et al., Generalized congruences - epimorphisms in CAT, Theory 
and Appl. of Categories 5 (1999), No 11, 266-280.

About Todd's answer:

just in case: he probably meant "[...] dominions equal to their *codomains*, 
this gives [...]".
