how is spot this morning?
i want to explore more about what you said in your very first post, that he's breathing hard and seems lethargic. is he that way today?
one thing many of us have notice is that our cats settle into a particular range of blood sugar and whenever they get into a new range, they get lethargic and don't feel as good. i liken it to my caffeine habit - uncaffeinated is the natural human state, but i have my daily diet dr pepper (i know i know) and THAT is my normal state. uncaffeinated and i feel like yuck and want to sit in a chair.
cats get accustomed to higher blood sugar ranges. almost everyone reports that their cat seems to feel better in 200's. but a non-diabetic cat's natural range is 50-120 on a human glucometer - so 200's aren't natural. the more the cat is in lower numbers, the more it will get adjusted to it and the better it will feel.
however, breathing hard isn't something i've heard described as part of it, so if that has continued, that would be a concern.
if your own vet isn't helping you, there are others around, i'm sure. if you need a suggestion for a good vet in your area, you can post here and ask. we come from all over the world and often someone will know another vet to suggest.
a 141 at preshot tells you that spot has cleared yesterday's bounce. he may bounce again. make sure when you shoot tonight you are doing it at 8:00-:15 or so. you can work back to your regular time, but generally you want 12ish hours between shots unless a cat is high enough to just move back at once to the regular shot time.
i would encourage you to post on the TR support group forum. you are testing plenty for following the TR guidelines, and a steroid-induced cat has the very best chance of healing and going back off of insulin. i'd love to help give you that chance. you can open a new thread here, and then you will have multiple people looking out for spot and helping you learn what to do to help him.
