Hi Sherri,
When my kitty was first was dx'd with diabetes 2 years ago, his glucose was in the 500's and he was walking on his hocks. Until we got regulated, the neuropathy worsened to the point where he would have to take breaks when he tried walking. It was horrible to see and it sounds like you are experiencing a similar thing with Skittles. I did use Zobaline and what AZJenks has written sounds spot on to me, especially the part of it getting better once Skittles is regulated. I used Zobaline for about a month, and between the insulin working and perhaps the Zobaline, I started seeing a difference. I can't be sure, but my guess is there is a lot of healing time where you don't really SEE a change, but when you do starting actually seeing improvement, it happens really fast - that was my experience, but I'm not sure it is the same for all. Blu seemed to stay on the hocks for a couple of months, then quickly was walking almost normally, and seems now to have all or most of his neuropathy reversed. I did little things for him to stay comfortable while it was happening - a chair near the bed do he could get up and down easier, and if you have a large home, maybe a couple extra beds or cushions on the ground along his "routes" if he needs to stop and take a rest. My sister has a cat bad that has a warmer in it for her elder cat - never gets too hot - might be worth getting to help ease his sore legs. I hope it is comforting to know that it will very likely be a temporary situation!
