Here are some of the things that have worked with Merlin when he wasn't interested in eating. Cats cannot go to long without eating otherwise complications can arise very quickly. Also here are additional links to read.

Additonal Information:
Treats: It is always nice to have treats available for your kitty especially when testing or when they decide not to eat. I like using Pure Bites. I have found it at Petsmart and other pet stores. It is freeze dried and the only ingredient is the meat i.e. chicken, duck, etc. If your cat likes it, then I would go to the dog section where it is cheaper than the cat package. It is bigger chunks but no problem in breaking it up. Another option is to use Bonita Flakes where you can find at your local Asian market. There is a link here somewhere in this site that has a list of low carb treats.
Lancets: Lancets are used to poke the ear to get blood for the meters. There are many different sizes lancets (gauges). It is recommended when you are first starting out to use a 26-28 gauge because it is a larger size and will make a bigger hole, hence easier to draw blood. Also, it would be a good idea to pick up Neosporin WITH pain reliever to apply on the edge of the ears and don't forget to alternate ears. It is a bit scary at first to start poking the ear, but eventually it will become easier for both you and your kitty. Some people even draw blood from the paw pad.

Testing: Many of us have picked out a special place where we test in our homes. We make the testing a routine so your kitty will become comfortable. Lots of love, hugs, scritches and treats are given before and after the tests. You want to be confident when approaching your kitty even though you are not at first. I know some here serenade to their kitties during testing. If the ear is cold and needs warming up, we just get a thin like dress sock and put a handful of rice in it and tie it up. Then place in microwave for about 15-20 seconds. Then test it to make sure that it is not too hot and place it surrounding the ear. Some take the sock before and after the test and massage the kitty with it...they love the warmth. Soon, your kitty will look forward to testing. Merlin would know when I would test him and he would go running to our place in the bedroom and turn himself around for me to pick him up and put him on the box.
Spreadsheets: Our spreadsheet instructions are
here. If you look at the signatures of the members here, you will see a link to their kitty’s spreadsheets. We keep track of all our tests. This is basically a place to collect data and help you to determine patterns, doses, etc. It also aids those that may be helping you to better understand your kitty. To further my knowledge on diabetes, I would make it a habit to read other kitty’s postings and spreadsheets. Even though they are all different and will be different than your kitty, it was still invaluable information.
Just holler if you have any additional questions.
