Jeankit, I’m sorry to hear about your Dottie having diabetes. *hugs*
My Alice kitty is diabetic. Like others have said, it can be managed. Giving insulin shots is not difficult and most cats adjust well to getting them. Just be sure to make the procedure a gentle loving time and Dottie will learn that she feels better for getting the shots and that you always give her lots of good love.
The link Kiplings Cat gave to the Cornell web site is an excellent source to read and learn from!
And the plastic pellets Jetta and Boo Boo’s Mom speaks of is the easiest way to get a urine sample. Substitute it for litter in a scrubbed clean and empty litter tray. After Dottie pees, then pour the urine back into the sample cup and take it to the vet for analysis.
I don’t know if it would work for Dottie but my Alice kitty has gone into remission after she began eating the special dry food I have for my Mandi cat who has a protein allergy. Mandi eats Royal Canin’s Hydrolized Protein dry kibbles available from the vet. It is soy based with no other carbohydrates. Soy has a very low glycemic index. Alice also gets some Fancy Feast canned food of the classic variety so there is no carbs in it, not even for gravy; just meat. Now, all that said, be sure to work with your vet to find what diet works for Dottie! Not all cats respond the same. Alice used to be on special diabetic dry food which didn’t help in her case. But obviously it does for many cats or it wouldn’t be so widely used.
Good luck. And always know that any of us with experience with having diabetic cats are happy to share our knowledge and help you find all the resources you need to get educated on how to help your precious Dottie.
