Dietary Fact Sheet

Rats are omnivores - meaning they can eat a wide variety of different foods of plant and animal origin. They will eat almost anything that humans do. However a balanced diet should consist of three essential elements:

  1. Dry feed
  2. Fresh fruit and vegetables, and
  3. Water

1. Dry Feed

Peters Mouse & Rat foods are specially formulated for adult mice and rats. The ingredients in our product range are carefully selected for their taste and texture, shape, size and colour, to provide variety and interest in your pet’s diet.

2. Fresh fruit and vegetables

Offer your pet rat a small amount of fresh fruit and vegetables each day. We suggest the following assortment, which your pet will enjoy:

  • Apples
  • Beetroot
  • Raw carrots
  • Defrosted uncooked peas, and
  • Cooked soya beans

Your pet may also enjoy some stale wholemeal bread. Too much lettuce, cabbage and broccoli can cause diarrhoea, so feed sparingly.

Ensure the fruit and vegetables are fresh and washed clean. Place the roughly chopped food in a heavy ceramic bowl that can’t be tipped over and remove uneaten food each night.

Introduce new foods slowly and in small amounts to avoid stomach upsets. This will also help you to identify your pet’s favourites.

Other Foods

Do not feed your pet rat any mouldy or spoiled food. Too much milk or cheese can lead to constipation. Meats and fats are not particularly good for rats and can cause unpleasant odours.

Avoid feeding citrus fruits or onions as the acidity could upset your pet’s digestion.

Rats enjoy nuts and dried fruit. Provide the nuts in their shells to help satisfy the chewing urge.

Chopped boiled eggs, pieces of bacon rind and marmalade jam are also enjoyable. Provide these foods as an occasional treat.

3. Water

Ensure your pet rat has plenty of fresh water as rats get quite thirsty. We recommend a gravity flow plastic bottle with a metal tube (sipper tube) as this keeps water clean.

Replace the water daily.


Peters pet rat treats such as Little GemsRollers and Fruit Crunchy Bar will provide hours of contented nibbling activity when your pet is confined to its enclosure. Great as a reward or training aid, Peters treats can be hung in the enclosure or mixed into the dry feed to add variety and interest to your pet’s diet.

The Gnawing Urge

Rats belong to the rodent family and have a single pair of incisor teeth that grow constantly. They need something hard to nibble on to wear down their teeth in order to prevent eating problems. You might consider placing a block of hard, untreated wood in the enclosure as a gnawing block.
