Have been using the Pet-Tinic product for over a year for my cat and have found no lower price than a few of the merchants at Amazon. If you know you will be using on an ongoing basis, think BIG and get the 4oz., vs. the 1oz.($10 vs. $8). The only minus, on Pfizer's part, is that the eye dropper you need for accuarate dosage is only available with the 1 oz bottle. My resolve was purchasing, locally, a 1 oz. bottle, then purchase the larger bottle, at the huge savings, and using it as a refill. Very quick and economical transaction.Get more detail about Pet-Tinic (4 oz) by Pfizer.
