B12 concentration: 50mcg/ml

Volume: 8ml per vial

Quantity: 12 vials



Formulated for:

Anemic adult cats

Provide additional support for immune system, nervous system, and digestive tract.



In many, but not all cats, our B12 formulation has demonstrated faster recovery and increased desire for food. Best used during the first 30 days of the treatment.


You should see clear improvements after using the first vial. Improvements include increased appetite, increased physical activities, reduction of fever, increased frequency of self grooming.


Administer the same daily dosage as non-B12 infused 20mg/ml formulation. Refer to our FIP Dosage Calculator to calculate the appropriate dosage for your cat.

Watch our instructional video on how to perform FIP treatment vials.
