Are you a member of our FB group? If yes, you could try posting there. Or you could also contact Diabetic Cats in Need (www.dcin.info) to see if they have someone who needs it.
I'm pretty sure DCIN would really appreciate it since Levemir is no longer sold in the US and we do have a few cats that need it. We would send you a pre-paid address label too. We'd need to know the size and weight of the package.
