Don't despair re: the number swings! This is typical at the beginning as their bodies try to adjust to insulin and new food. If you want to feel better, just look at Girlie's spreadsheet from 2017: Insane drops and bounces! She settled down finally when I switched her to Levemir (Detemir), and she's got lovely numbers now, but the early months drove me crazy.
What food are you feeding? Are you feeding wet food? I drove myself crazy as well trying to figure out what low carb, medium carb and high carb food I could get here in Australia. You need all three so you can deal with quick drops or a hypo incident. Absolutely IDEAL for hypo (drops into dangerous lime green territory) are the
Weruva Cats in the Kitchen pouches: just cut the edge off and squeeze the gravy out and give it a tsp at a time if you have a hypo number. This enables you to get higher carbs in without filling their tummies too quickly. You can find links to the hypo toolkits and how to handle a hypo on
this sticky.
The
Weruva Cats in the Kitchen cans are also really good as far as being low carb and low phosphorous (important if you have a kitty with kidney issues).
I've attached a list from Dr Pierson's US food chart of food with carb values, phosphorous, etc. Just be aware that the Wellness cans (e.g. Beef with Salmon, etc.) have changed their ingredients, so they're now much, much higher in phosphorous. I've also attached my Excel SS (__MC and HC.xlsx) that has a tab for MC (medium carb and high carb) and LC (low carb) food that I keep taped to my wall so I can easily know what to give Girlie when. The parenthetical references after the LC foods are the phosphorous levels.
Are you familiar with the protocols (star low go slow (
SLGS) and tight regulation (
TR)? It takes time for their little bodies to get used to having insulin again, so you might see wild swings in numbers. Girlie used to bounce really high when she got a yellow number or a blue number because her body wasn't used to having lower numbers. This is very common. I know how hard it is to wear patience pants (as they say here!), but it's worth it and we've all been there with the frustration and anxiety. You're in a great place: FDMB helped me get Girlie to where she is today and also saved me from losing my mind (as my vet didn't really know much about how to handle feline diabetes; many don't and advise dose switches that are too drastic too quickly - a source of frustration for many starting out on this board...)
I hope this helps!
I'm from the US originally as well: D.C. I understand that you're a transplanted Yank as well?
