His numbers are pretty consistent, prior to eating, and not going very low at +6. I'd be tempted to up the dose again on Poopy if I were home to watch him and those were his numbers. I see the last time you did this Cassie's numbers went higher. When I think I'm going to up Poopy's dose, I pay a bit more attention to the carbs in his food (0,4,8?) to see if that is playing a part in his numbers. Poopy also tends to go a bit higher when I up his dose, then dips a bit, then climbs back up.
Weird cat.
Wouldn't it be nice if they, the cats, all followed the same rules? LOL Rules and cats. Yeah, right!
