Yes. All vertebrate animals (dogs, cats, rodents, birds, horses etc.) naturally produce GcMAF proteins and therefore can benefit from supplementing it via our products. Our sublingual spray contains no additional ingredients except for saline solution and is suitable for all animals, however our creams do contain many addition ingredients which may be allergenic to some animals. That is why we developed GcMAFpets – a separate range of GcMAF gel products specifically for animals which you can purchase here.
