Re: Newbie- 6/7 Oliver +7 403 +8 421 +9 419 Need doseage hel
That's great that you had labs run. I'm assuming that Oliver's hyper-T was under good control when the labs were drawn. Hyper-T can effect BG levels.
I would talk to your vet about a dental. At 16.5 yrs young, it's quite possible that Oliver has tarter on his teeth. Tarter deposits can cause the gums to be inflamed and the inflammation stresses the cat's system. Any sort of stress can cause a food controlled diabetic to lose regulation. Although his blood work didn't indicate that there's an infection, there can still be an inflammation.
I would strongly encourage you to pick up Ketostix at a pharmacy. This is a method to test for urinary ketones. (You dip the paper end of the strip into Oliver's urine and it will change color to let you know if ketones are present and if so, how much.) Until there's improvement in Oliver's numbers, given that the vet noted the presence of ketones, testing is your best way of avoiding what can be a life threatening situation. Ketones develop if there's not enough insulin, an infection/inflammation is present, and a cat isn't eating. Ketones can go from a level that's manageable at home to a critical situation so testing can save you a great deal of anxiety and money! Adding water to Oliver's food is an excellent strategy. Fluids help to flush out ketones.
Ordinarily, I wouldn't suggest that someone who's relatively new to managing their kitty's diabetes shoot early. (And early shot acts like a dose increase.) However, given where Oliver's numbers are, it's not a bad idea! Just remember that your shot tomorrow AM is 12 hours from when you shot tonight.
Given the ketones, I would have suggested dropping Oliver's dose just a little -- to 0.75u. It's up to you if you want to stick with the 0.5u. If you do, it's very important that you pick up a box of Ketostix. They are available at pretty much any pharmacy and you use the same ones for Oliver that you'd use for a human.
