Important Order Information

Please fill out the CUSTOMER INFORMATION FORM to expedite order processing.

VetImmune® always recommends that cat guardians establish diagnosis and order Polyprenyl Immunostimulant™ through their veterinarians. VetImmune® is also an ethical company: we believe cat health and well-being issues are paramount. The impact of the COVID-19 pandemic has been felt by all of us, including veterinarians and specialists who face an increased workload and reduced availability due to the unique nature of the pandemic's restrictions. As a result, we now conditionally accept orders for Polyprenyl Immunostimulant™ prior to veterinarian consent to allow access to urgently needed treatment as early as possible. If you have not yet done so, please fill out our Customer Information Form available here.
