Yes, there will be varying degrees of "food" and "water" that you will need to give your pet.
edit: Anyways, still working on the admin side of things. Released I never added an "edit pet" feature. I should have it all finished today though. Coding items won't be hard, but it will still probably be awhile before the user end get coding. More like 2 weeks instead of the 1 week I previously mentioned. I hope to get it done by june though =D
