Anyone have any experience with the ADVOCATE PetTest meter? I bought this when my cat was first diagnosed not long ago but barely used it. I now am getting the hang of home testing but not sure how reliable it is. I am thinking about switching to the Relion since everyone here seems to love it and for it's price. This may be a stupid question but is there any thing different I need to do when using a human meter on a cat? Or it's just take his blood and check the number. It's confusing they make BG meters specifically for animals, is it just a marketing thing or is there some difference in how it reads blood etc? Thanks!
