Hello, I have a cat that just turned 6 years old. Out of the blue about a 6 days ago my cat was rushed to the emergency vet. Her glucose levels were over 700, she was very dehydrayed. They hooked a drip up of humulin insulin and stuff to hydrate her. They got her glucose down a bit. We transfered her to her main veterinarian the next day instead of going back to the other emergency clinic. We are trying to adjust her insulin.. however 1 1/2 units and then 1 1/2 units about 8 hours or so later dropped it to 84 on the human meter, because she isn't eating much or drinking I've come to the conclusion I have to hand feed her at night and shoot water in her mouth slowly to keep her hydrated. 4am today her glucose levels crashed at 50 on the human meter. I test from her ear as i seen in forums. I gave her honey and at 7:45 am her glucose was 277. I gave the 1 unit insulin shot of prozinc. Tested her glucose at 12pm of Course though now it read 565 she ate about an hour or so of testing. Does anyone have any answers about my situation? I am feeding her fancy feast can food. Due to she doesn't like the DM Pro plan she threw it up and now won't eat it. She has been to her regular vet 2 times now once to watch her from emergency vet to because her levels went up to 700 again. She gets antibotics , hydrates there.. not really sure why the sudden spikes in glucose. Will be testing again tonight around 5pm central time. Any thoughts or help would be great. She is eating and somewhat drinking however sometimes I feel she forgets ,she has walked up hallway to kitty box once since hone again or I have to pick her up and bring her but she walks down.
