I'm a bit stumped on the spelling of the ending of 12A, personally I think it is poorly worded. Eating food of both animal and vegetable origin, or any food indiscriminately? OMNIVOR*S
If it's really only 9 letters, perhaps they mean Omnivores, i.e. examples of creatures that eat "everything", though I agree "eating" suggests an adjective rather than a plural noun
Thanks for agreeing Maurice, I wanted to put ous at the end or even us but theres not room for ous and us is not correct, so I can only think of es too.
