What to feed a pet rat
The basis of the diet is a complete rat food: rats can't pick through pellets (Complete) and eat them whole, while with grain mixes they choose favourites, so don't overfill the bowl. An adult rat needs about 20–25 g of food a day.
Add vegetables, a little fruit and protein — boiled egg or lean meat once or twice a week. Treats like crackers are for training and in small amounts; fresh water must always be available.
