Hey I've had my cat ozzy for 3 years (he's 4 years old) and got the diagnosis about 2 months ago. He's drinking and urinating lots as are his symptoms. Since last week he's been on 2 units every 12 hours. He is so skinny and lethargic, I'm seriously worried that this isn't working. I've rung the vet again and she says it's just him not quite where he should be yet with the dosage. Today I noticed he's having trouble drinking. He's slurping the water but ever now and then he ends up snorting the water and making himself sneeze. It upsets me not being able to do very much to help him. Am I doing enough? What if I can't help him? I'm not giving up on him but I feel like I'm failing.
