Hi Renegaderem, and, of course, you too, sweet Daisy (love her name!!!),
Sometimes less is more. It may be that Daisy was started at too high a dose. Maybe not. Maybe she's just being a cat. Maybe she's a sugar cat who's pancreas still kicks in from time to time... You know Daisy better than anyone else on the planet, so I'm thinking you'd be the first to know if she is sick and therefore needs to see her vet...
Because you are home testing (YAY!), you will probably figure this out. Then again, she is a cat... ;o)
Because you are suspecting rebound, my humble suggestion is to start over/continue with the 1 unit dose, and cross post your questions/results both here and on the PZI Support Group forum. For some strange reason, it's just easier to add a bit than to reduce as more readings/information become available; thus, the FDMB's start low, go slow approach... Can't explain it; but, have seen it with my own two eyes -- with two sugar cats...
It is most interesting and rewarding sharing life with a sugar cat, isn't it, Renegaderem?
Please keep us posted kind of encouraging hugs,
Deb and Nikki -- and, Giz, forever dancing in my heart...
PS: She's eating okay, right? Do you catch pee and test for ketones?
