To clarify when I say "a few bits of fish fillet" sometimes in the mid-week I mean about the size of one pinkie and it seems much less solid than a mouse. About the equivalent of a bite for a human. I'll split it into two or three pieces to easily fit in her mouth, seemed like an OK snack.

Still, I've just been going by advice of a few friends. I don't want to overfeed her, but also don't want her to be uncomfortably or unhealthily hungry.
