Wurt can eat electric milk?

This isn't really a bug, but I found myself disappointed that Wurt can eat dairy items like milky whites, butter, electric milk, and crock pot dishes with dairy. Merms have been confirmed to be amphibians, and would therefore not be able to ingest dairy. I feel like these foods should at least give her a health drain or sanity drain. I know this isn't really a bug but I would like to see it fixed.
