Lots of good news in your condo tonight!!
There's also a ton of information. I'm going to try to give you a short summary so information doesn't get lost.
- The good news is the ketone levels are coming down. DO NOT become complacent. Ketone levels can rise quickly. Please keep on your toes and doing what you've been doing (because it's working!!).
- Test for ketones whenever you can. This is the best early warning system you've got.
- Stick with what you've been feeding. Right now, you're balancing all of the insulin you're giving with food. If you lower the carbs, you may need to lower the insulin and that's not a good idea at the moment. (When Desi's Tawny was dealing with the same issues as Sasha, I told her I didn't care if she fed Tawny a hot fudge sundae. Calories help to combat ketones.)
- Keep being as careful as you're being so you don't confuse which insulin is which. If you're not sure, start over. Wasting a syringe that's filled with insulin is far less expensive than shooting too much R.
- Know that there are a lot of people here to support you. Many people may not be posting in your thread because they want to make sure you are getting the information you need at a critical time. If you need anything, ask.
As for the vets, I would strongly suggest you get a copy of Sasha's records from the vet hospital. In particular, get the ultrasound report, lab tests, and the notes from Sasha's hospitalization. I'm not comfortable with someone saying that there is a kidney infection and then saying, "Oops! My bad. No infection." Have the information in your hands if for no other reason than if you change vets, you have Sasha's most recent tests. Baytril is not a trivial antibiotic and antibiotics should not be given, "just in case." That's a great way to cause antibiotic resistant strains of bacteria.
Most vets haven't a clue about whether home testing stresses a cat. The reason is that most people don't home test. The vets don't have a baseline. On the other hand, if people don't home test, they have to go to the vet for curves and fructosamine levels and the vet makes money.
You've been doing great. Please do try to get some rest. Hopefully, Sasha has turned a corner but there's still a way to do.
