Hello!

I get the following compile error below in the complete program below.
Any suggestion

It's hard to say for sure because you haven't included your using
directives, but I suspect the problem is that you're missing:
using System.Collections;

That's required to let the compiler know about the nongeneric
IEnumerator type.

After that you'll need to add a Feed method to Animal.
