Waving at you from the west coast of BC.
A couple tips that might help the student budget. First and foremost, the Alphatrak is not necessary. Those test strips are so expensive. Our dosing methods actually discourage the use of pet meters, as they were developed with caregivers using human meters. The AT's are a fairly new invention. In Canada, the Freestyle Lite is one popular option. Similar blood drop size needed. But there are other human meters that work well too. Ebay is one source of cheap test strips. Tip number 2 - many cats get tired of DM. Ingredients aren't the best. It's not really diabetic food anyway. You'll see it's called dietetic. The manufacturer was forced to change the name. There are loads of commercially available pet foods under 10% in carbs that you can use instead and again are cheaper. Note, you can use the AT and feed DM if you want, they will just cost you more.
Since you are feeding low carb wet food, you can use either dosing method. The choice is based on your lifestyle and goals for Alti.
But I see you made some changes to the spreadsheet and the US tab is now missing. Lots of people who help with dosing here are in the US, and need to be able to look at that tab to help. Plus the server is hosted in the US so we use their numbers by convention. The spreadsheet also shows just 1 dose given a day. I presume you are doing two? The previous version of the spreadsheet I saw had more data I think?
