Hello There,
The simple answer is "Because you shouldn't ". If you really care about your kitty, you wouldn't dream of it.
Trust me, you WILL be able to do and will WANT to do it!
I have 2 sugar babies. Jack and Samantha
Jack was dx @634 and was wobbly walking and lost a lot of weight. He needed help quickly. He was never a cat to be held, but was affectionate. I think he was so sick he just didn't have it in him to resist. When he got better, he got feisty when I went to give him a shot but not much. I can still test him without much of a peep. Not like the youtube video, but close.
On the other hand, I have Samantha, a 15 lb. calico. She has always been affectionate but has insisted that her nails do NOT need to be clipped. See Daddy, I ripped a hunk of skin out of you to prove it.
She was in better shape physically than Jack, but she still squeals and is leery of me. Even with treats, which she loves, she just kinda puts up with it. Just the same as it was with her nails or the vet.
I cannot stress to you the importance of testing. Without testing, keeping the BG under control, let alone trying for remission, would be next to impossible and a shot in the dark at best.
I too thought it might not be something that I could do, with even Jack. But my love for my kitties put that fear aside and made it something I HAD to DO! His well being and life were in my hands. I was not going to let him down.
This is a great place to get information and help with treating your kittie. While I have only been here for 49 days, I learned so much that has helped me to get Jack to the point where he has been off insulin for 13 days now. Tomorrow is a milestone for him, after 14 days, most say he is in remission.
He will still be on a strict High Protein, low carb diet (which is a must) but at least he will not have to have twice a day injections of insulin nor as frequent pokes for testing. Still testing at least once a month, but a lot better than 4 times a day.
While I have not gone into any of the real details of the process, I will leave you with this and let you digest it.
When I and others see your response, we will be there for you giving you all the information that you need to help you and your kitty.
Take care and all the best to you and yours,
Kevin
