Rat Mix & Pellets
Most pet shops sell mixes specifically designed for rats or small rodents. These usually consist of grains, seeds, pellets, biscuit and dried vegetables.
There are also rodent or rat pellets sold in some stores. These are compressed food pellets and although they are designed to meet a rat's nutritional requirements they do not give the rat any variety. Rodent or rat pellets with some basic rat mix will also provide an adequate main diet.
Food mixes specifically designed for other animals should not be given as these may not be suitable to meet your rat's dietary requirements and may even harm your rat.
Rat mix does not perish quickly and so may be stored for some time in dry conditions without problem.
Any changes in diet, even changing to a different rat mix, should be made gradually as a sudden change in diet can cause your rat to become ill.
Rats should be fed a basic rat mix as the main part of their diet and this can be supplemented with other treats.
