So I've been buying Zobaline for diabetic cats through Amazon. With shipping it comes to about $32.00. Is there something cheaper I could buy that's the same thing? Yesterday we found out my bfs cat has a motility disorder after 2 months of back and forth to the vet (and about $2,000 on top of Angels expenses). And his monthly meds are going to run us $125.000. The Zobaline has been great so I don't want to risk it unless there really is another option that is the exact same thing. Thanks!
