I wonder if certain pet food products can be used for feeding more than just one species of pets?
For example, there are plenty of worm products being made as fish food. Such as bloodworms or blood worms, and Tubifex worms, both in frozen form and freeze dried form. They are high in protein and minerals. On the bottles of these worms it often say they have enhanced vitamins. Fish are delicate species, as they are among the pet species that can die the easiest. If fish can eat these worms without ill effect, can these worms be fed to worm eating birds and lizards?
Same goes for certain pet food made for dogs and cats. Can some of them be used for both dogs and cats? Most rat species also prefer to eat meat, can they be put on a diet to eat dog and cat food?
Some larger species of fish have to be fed with feeder fish. Can the same feeder fish be fed to lets say cats, snakes, and some bird species feed on fish?
