Looking to replicate something like this (with a weekly/monthly/ect views, maybe monthly view can look different since it would be too long to scroll, but anyway, it looks like arse but was just giving it a go), but didn't want to have to create a full webapp (with CRUD data inserts, pagination ect... its certainly doable, but just annoying to implement). This is just a simple index view in a random framework I found, with some real, but pre-canned data via db seeding (so at least I can re-create it easily). Just thought there could be something easier that already exists and i wouldn't have to be re-inventing the wheel. Have a paper version of this, but its too hard to keep track of different foods via paper.

Spreadsheet sounds interesting (read easier) to try, though I am not quite sure how to do the lookup bits. Would it be something like one table (sheet) of events feeding from say, food type table (sheet) and some kind of a month view that can accumulate events on the same day?

PS: yes got a vet appointment coming up soon.
