Possible DKA on Health need more experienced eyes please

[MommaOfMuse]

We have a newbie on health that sounds like her cat is going into DKA....could use some more experienced eyes please, vet doesn't sound like they are being terribly helpful. Cat is testing the darkest color possible on Ketostix and not eating well.

Thanks in advance,
