No problem. Glad to help.
I wish I had known about dry food causing diabetes before my cat got diabetes. I could have prevented it.
Here's a good page to read up on about how most dry foods are bad for cats, especially diabetic cats: http://www.catinfo.org/felinediabetes.htm
There's a list of safe wet and dry food on this page. http://www.felinediabetes.com/diabetic-cat-diets.htm
And here's one about wheat gluten: http://www.felinediabetes.com/glutenfree.htm
I got all my information by studying these web pages, and from the people on the board that I posted above. I recommend any caretakers of diabetic cats to post on that board because people there are really knowledgeable about diabetes, more so than most vets.
Tommycat, I know the idea of pricking your kitty's ear is not an appealing one. I felt the same way before I started home testing, but the people on the board encouraged and guided me through it. Believe me, it's for the best. Not only is it safer since you can prevent hyperglycemia attacks, but it will save you so much money in vet bills. You can just use your own glucometer, although some glucometers are more accurate than others. I use Freestyle Freedom since it's the closest accuracy to the one my vet uses, and needs just a tiny bit of blood. The strips are expensive, though. The cat actually doesn't feel much on the outside of the ear. Here's a very informative video on how to home test: http://www.youtube.com/watch?v=_zE12-4fVn8
I find it easier to use a lancet device. If you're worried about your cat running away from you because of the tests, try to make it more pleasant for him. Give him a treat before and after the test. There's a list of safe treats on that page I linked above. I've heard a lot of success stories with using treats, and how the cat will run up to his/her caretaker when it's test time. If you make it into a routine it's a good bet that kitty will be used to it in no time.
As for Lantus, I got lucky and only had to pay $20 a month. My local vet clinic sold it in small amounts, and since my guy didn't get more than 1 unit, it would last way over a month. Maybe your vet can sell it to you in small amounts as well so it won't cost so much. There's also a cheaper insulin a lot of people like using called PZI which is made especially for cats. If you're in the US, it's easy to get. But it's no longer available in Canada. I prefer Lantus anyway.
Hope your kitty continues to feel better!
