We are particularly proud of this product, which integrates the functions of complementary fodder and mineral bedding for exotic birds. Different types of sands and gravels are a very precious ingredient of the daily diet of birds that live in the wild. Pterosan acts in the bird's digestive system as perfect material that assists in its digestive processes. This snow-white, processed river gravel has two functions: Pterosan is rich in calcium, it contains specially selected shells, coral reef fragments and easily assimilable C vitamin, which is particularly important for the proper development of birds. C vitamin being included in the product, makes the birds body immune to illnesses and is helpful in recovery periods after infections, it narrows down the risk of contracting illnesses when the bird is transported, during feeding changes, helps the pet's organism in getting rid of toxins. Anise, which is present in the product, has a very good influence on digestive system's microflora, and serves as a perfect barrier against any types of parasites; it also disinfects the cage, keeps its inner and outer space fresh. The scent of anise is one of a few smells that birds can fully accept. Thanks to the use of the Pterosan product, the bird cage will not only be an aesthetical, but also a hygienic element of every flat's decoration.
