My kitten is dropping too fast and too low on the Vetsulin. We've been at this for about 1.5 months, and her dose of Vetsulin is .25U twice a day and she's still dropping hard. So I'm considering trying Lantus. My plan was no Vetsulin tonight and start again tomorrow with the new insulin. I don't know what dosage the vet is going to recommend. Does anyone have suggestions / experiences they can share?
