Re: 2/4 Rocket AM BG 67=NS
Good Morning Claudia and Rocket-
Im very sorry to hear about the results. :YMHUG: Tho Im glad you know what you are dealing with, rather than continuing to wonder. That wondering mind can really do a number on us!
I dont know if it helps to share my experience with Latte, but I can...just in case.
Latte had Acute Renal Failure, then crf. After a few yrs we did a u/s because her crf was stable, but she was not eating for a VERY long time. I syringe fed for a year despite being on all the possible medications for nausea, appy stim, etc. The u/s revealed IBD and/or lymphoma, along with possible chronic pancreatitis. We did not do a biopsy to determine because of her condition and the risks involved. I waited it out a bit until we had an emergency one night. That is when she got her first dose of steroid (dex shot, followed by daily pills). It took a few weeks, but huge improvements were seen. She then became diabetic (from the steroid). At that point I had to make a decision to pts, or restart the steroid, knowing I was going to keep her diabetic for the rest of her life. It was really a hard call for me. When stopping the pred proved to be life threatening, I restarted. She spent the remainder of her life (almost 10 months) on the steroid. It certainly did cause a headache with the diabetes. But generally her QOL was good.
I know you are worried about how it might affect his kidneys, BG's, etc. I was too. But the alternative of losing Latte didnt feel right either. I cant say my decision to use the steroid was a good or bad one. Its what I chose after much contemplation, and many talks with her. It gave us a total of 14 extra months together. Tho stressful at times, it was worth it. I think if you could talk with her 'spirit' she may just say the same thing. ;-) No one can guarantee how much MORE time a steroid would give you and Rocket together. But it could make the remaining time, no matter how short or long, much better quality.
many hugs to you two in your journey together.
ETA: Also keep in mind, ecid...for some cats, steroids do very little 'damage' to BG's. In some, it will even help their bg's improve if high, because they start feeling better. One never knows!
continued thoughts and prayers for both you and Rocket. unless someone suggests there's an issue, I'd definitely give him a testing break until you start the pred.
