Hi. I am in desperate need of advice. My 16 year old had a urethra blockage last Sunday. His blood sugars flew off the charts causing seizures. He is now blind. I have had him home since Tuesday. He will not eat unless I hand feed. He is starting to lick off the plate. He just lays around very limp. I have a vet appt in an hour and need advice. Would you continue to try? I'm so lost right now. My heart is breaking.
