I am just so glad you now have him back at home, and he is safe again. It's hard losing sleep, but at least you got your fur-kid back.
It's your spreadsheet, so you can use it as you wish. However the colors don't show up if you add comments within the AMPS or PMPS readings. You may want to post comments in the far right column. An alternative - you can add a comment to a cell. Just click on the cell, then at the top menu select "insert -> comment". It is the same in excel too.
I am also glad to see the move to dose 3.25 units. Pretty soon Tucker will start getting some blues and we can all celebrate.
We had our entire house tiled in 2011. Every square foot. I helped by moving furniture. Painful to live through. We also had them use epoxy grout. It was expensive. They mix a small bucket and grout as normal, but clean it with vinegar (acid). The result is a 100% non-porous floor. The tile guys complained through each bucket load they mixed and applied. But they got paid...and I don't have to live with them!
Cat pee, dog pee, poop, barf - nothing seeps in or seeps through. And the grout lines never really get that dirty because they do not absorb anything. Sure, ink will stain them. But everything else just cleans up.
We had 3 cats at the time (Leo, Scoobs, Chinus), and Scoobs has left us since then. They didn't mind it so much.
