Did you feed the cat this morning? Would the cat tell you if you did? Of course not – food is an indoor pet's main source of entertainment. Using MagTag, we can create a clock that sets itself and allows you to save a reference to the last time you fed the cat – simultaneously maintaining your pet's healthy weight, and your sanity.

Bonus: it's compatible with dogs as well.
