Just started Young again about a week ago, and right now, Dottie is off insulin. I am still continuing to test several times a day to keep an eye on her. I always will.
I think diet in general helped a great deal, but to be fair, Dottie had a tremendous history of stress on her before her dental surgery, and that stress is gone now, so I can't say that Young Again did it all. Her numbers were headed down anyway. Hallelujah!
Dottie is also eating wet food...I'm using the dry for emergency grazing..because for health reasons, there are times when I simply need to pass out or am laid low for relatively long periods. Going the past two months without needing serious medical assistance has been an unusual break for me. I put it down to the sheer adrenalin rush of caring for a diabetic cat..but I can't always keep that pace up.
I'd rather have dry food available than no food at all. Hubby is willing to give shots, but isn't at all agreeable about going through handstands for feeding a stubborn kitty. If I were to go into hospital, I would need a backup food I can rely on, to get those calories in.
I'm also introducing the furkids to Stella & Chewy's line of freeze dried raw..which I like very much..(to serve, not to eat

)...and hope to get them over to that, eventually. You might consider trying that, too.
It's always preferable to have a cat on wet food..their species were originally desert dwellers. They don't always drink what they should when they eat dry..... But if they are extremely stubborn, and...say for example, they are sick, not eating at all..but
are willing to eat dry..... striking a bargain with them, using dry food like Young Again can an option.
Is it perfect? Nope. Just don't give up on wet food...try to adjust them over time until they're eating wet instead of dry.
