Very nice work Foxicube! I wish the game was a little more indepth (really, no negative consequence for not feeding her for a whole week?) but it is pretty damn great.
For anyone wondering how to get the "Too Much Teeth" achievement, you have to get max affinity/love with her. This can be easily accomplished by petting her several times, waiting until you have almost no energy left, and then feeding her (assuming you have the meat to do so).
