I don't give dosing advice on Facebook, or here on FDMB unless I really know the cat, like Suki and Crystal in the LL forum.
I have, however, spent this morning getting up to speed on Poopers, the threads here on FDMB, and all the advice you've been given, Ryan. And you've received some excellent advice from the people here. The people advising you are the people who helped me realize I needed to get Cobb tested, on a great insulin, and, by following their advice, we ultimately got him in good numbers - earning reductions. We went from 31u at his highest (which I stopped at, due to the cost of the insulin) and he was on single digits of insulin just before he passed away.
Given the dose Poopers is currently at, you're going to hear more frequently that it is time to have him tested. I know how frustrating it is to hear that when you don't really have the money for the tests. When I found FDMB I had just had a baby and quit my job. We were living on one income with the bills and debt that we established on two incomes. It was also the same time we switched from Prozinc ($80 a bottle) to Lantus ($225+). So I completely understand your cost concerns. I shared my experience (and stubbornness

) with a high dose cat on the FB thread. I think we were up around 18-19 units of Lantus before we actually got the IAA test done. The vet who drew the blood grossly overcharged us with an insane markup, but what was I going to do. Her markup on the acro test was one reason we decided to not have it run. If you decide to have the tests done, see if the vet can work with you on a payment plan.
If Poopers has a high dose condition, there is no better place you can be than right here because so many of us have been through it. We can teach you the techniques that we tried, the techniques that failed for us, and the techniques that had success. What is most frustrating about this disease is that what works for one cat does not always work for another. There are some cats who have been on 50+ units of insulin twice a day. The techniques they used would have been dangerous for a cat who is on much less insulin, even if that cat were high dose.
I know people have said to be patient before.

It never gets easier to hear! It took Cobb over a year on insulin to see any kind of meaningful results. My husband and I went back and forth on what to do -- from stopping any kind of treatment and letting nature take its course, and yes, we discussed putting him to sleep because we were spending A LOT of money and we felt it was just being thrown out the window! I've been MIA from FDMB since January (I've popped in every now and then) when Cobb passed. I definitely needed a break! But I'm trying to check back in more often than I have been.
I hope you'll stick around, ask lots of questions and follow the great advice you're getting! You really are in a great place!
