Tokays consume all insects and arthropods they are able to overpower. This includes various species of crickets, locusts, roaches, mealworms, giant mealworms, beetle larvae, and even beetles. Adult Tokays even have a taste for pink mice. Keeping them on diet of just one type of food, be it mice or a certain insect species, is not a good idea, though. After having eaten a mouse, Tokays will often produce faeces that exude a strong smell and are sometimes rather liquid. Tokays sometimes also lick up yoghurt (GROSSMANN 2008b) or even feed on cat food offered on a plate or in a bowl, but most specimens require a lengthy period of adjusting to this type of food.
The food offered should be routinely dusted with a vitamin/mineral supplement for reptiles 1-4 times per month. This is not quite sufficient for females during the reproductive season as they now have a much increased need for calcium. Making available crushed cuttlefish shell in addition takes care of this supply. In fact, females should have free access to small crumbs or pulverized cuttlefish shell at all times.
