I’m assuming you meant ProZinc insulin and if so there is unfortunately not a cheaper alternative. While less expensive human insulin can on rare occasions be used successfully in cats it usually does not provide good control of diabetes. You also need to start over with dosing and frequent monitoring when switching from one insulin to another which would increase cost. It’s probably best to stick with ProZinc if Mikey is well regulated.
