Tracker for elderly or sick pets

I designed this dry-erase board to help me keep track of Zoey's medications, bowel movements, and feedings. Between my SO and I, it can be hard to know when she ate and when she took certain meds.  I found this super helpful, so now I am selling the design if anyone else can benefit.  

I also welcome any suggestions for improvement!

So after the popularity of this design, I went ahead and made another one that I myself use in the stable to keep track of my horse care, vet visits, deworming, and so forth.  Here it is if you would like one as well, for yourself or a gift!
