Seal oil is the purrfect supplement because it contains not only DHA and EPA, but also DPA – a third powerful omega 3 fatty acid that enhances the amount of the other omega 3s in the body.  DPA is 10X more powerful than EPA! And because seal oil comes from another mammal, our feline and canine friends can digest and absorb these essential fatty acids much easier than fish oils and other sources of omega-3!
