Burgess Excel Rat Nuggets is a great, complete food that when fed alongside a continuous supply of clean, freshwater offers your rats all they need in order to stay happy and healthy. If they are given the opportunity rats will selectively feed, meaning that they only eat parts of the diet they need, so it’s important that you feed them a balanced nugget rather than a muesli. These balanced nuggets should be fed in an interactive way, for example, by hiding their food around their housing in order to keep their brains active and encourage natural foraging behaviour.
