Godzilla eating other monsters?

I was watching one of my favorite Godzilla movies (Tokyo S.O.S) and looking at the remains of Kamoebas, a thought occurred.

Has there been any instance of a kaiju eating another?

Godzilla has only ever killed, I can't remember a time when he has consumed an enemy.

I am excluding Godzilla's fight with Orga because Orga didn't succeed in his consumption.
