I have a 12 year old, diabetic, spayed, feline. She has been insulin dependent for approx 5 years. Occasionally, she may go a week or more and require NO insulin. She's been on Humulin-Ultra the entire time. Has anyone ever had a bad bottle? This bottle is less than two weeks old, but her #'s are over 300 when normally she is just under 200? :confused:

Did you accidentally leave it out of the fridge? It can go bad pretty quickly when not chilled. Also, our vet recommended a switch from Humulin to PZI, which is formulated especially for animals. Both of my diabetic cats receive insulin daily - I've never heard of being able to go a "week or more" without.

When was the last time a glucose curve was done by your vet? The insulin dose may need to be changed. Also, I have never heard of any other way of regulating diabetes in cats or dogs where you did not give insulin daily.
