Mr Johnson’s Supreme Rat and Mouse food is a complementary feed and should be fed together with suitable fresh fruit and vegetables. Fresh clean water should always be available.

Overcoming selective feeding:

Rats & mice if overfed, can sometimes selectively feed and may leave their less favourite ingredients in the bowl until last, resulting in an unbalanced diet and nutritional deficiency.

To help overcome selective feeding your rats & mice should be fed twice a day, dividing their daily requirements into two meals, feeding morning and evening but only refilling the bowl once empty.

Changing your rat and mouse's diet

Your rat or mouse's diet should never be altered suddenly as abrupt changes could trigger digestive upsets, especially in baby or stressed pets (for example if they have moved to a new home). If you want to alter their diet, it is recommended that this change takes place gradually over a 7-10 day period. This can be done by mixing small quantities of the new food with their existing food and increasing the proportions until it is fully changed over.
