Review Summary
Your implementation passes all functional requirements and tests - the Animal class hierarchy, hiding mechanics, and bite behavior all work correctly. The only issue is a checklist preference violation at lines 31-35 where indexOf + splice is used instead of filter for removing dead animals from Animal.alive. While this doesn't affect functionality, the checklist recommends using filter for better code clarity since it creates a new array rather than mutating the original in place. Since all core requirements are met and tests pass, I'm approving this submission. Consider refactoring to use filter in future work for cleaner, more functional code style. Great job on the complete implementation!

This violates checklist item #1: 'Avoid nesting loops (indexOf + splice), use filter instead'. The splice method modifies the array in place while filter creates a new array - filter is the preferred approach for removing dead animals from Animal.alive.
