The father of kits is NEVER mentioned.

I know, I know. Toms don't usually raise kits but at least mention them somehow as the father.

* Depends. If the father isn't relevant, they don't have to be mentioned. Just don't fall into the trap of implying fatherhood is less important than motherhood, or that absent fathers should be normal. The Clan raises the kits and all, and that's enough justification on why the mother doesn't need to name the father.
