Re: PLEASE HELP
hi and welcome. There is a lot of valuable info here. Poke around the site and check out the FAQ and the Health Links especially.
Since you have financial issues, you may want to request a Newbie Kit immediately so you can get a meter and strips mailed right away. Getting your cat on the low carb wet food, as per the Janet and Binkie list, is going to be critical. It doesn't have to be expensive food either. I just saw the big cans (13 oz, I think) cans of Friskies pate' for 84 cents each today at Walmart. That would easily feed a cat for a day.
If you can get your meter and get testing right away, then you could possibly avoid the cost of some diagnostics such as a fructosamine test (3 week average of blood glucose levels). You would be able to bring the testing results to your vet and he may be able to determine if your cat is diabetic from those readings, and from regular blood work which would probably be necessary to rule out other causes. If your cat is diabetic, the low carb wet food will help a lot but your cat will almost certainly need some help from injected insulin. Without appropriate insulin dosing, he can get very sick and need hospitalization. Also, a cat's best chance of becoming diet-controlled occurs when the diabetes is treated quickly, and the BG is brought down. High BG damages the pancreas over time, and of course the cat can get very sick too. High BG means sugary pee and saliva, and this often leads to urinary infections, dental infections, poor healing, etc. High BG also leads to nerve damage which is why the cat's back legs don't work so well -- but this is reversible especially with methylcobalamin treatment and of course reduced BG. The high BG can also lead to a very serious condition of ketones in the blood, which can be fatal in short order, and requires hospitalization to treat. I say all this so you realize that even with an immediate diet change, you really do need to get the cat in to the vet quickly.
If you go to catinfo.org, you can learn a lot about basic cat biology and their nutritional needs.
If you post your general location (nearest big town, state), then someone may be able to give you hands on training in hometesting your cat. But there are plenty of people who learn by watching the videos.
I know you will have a lot of questions, so don't be afraid to ask away.
