Fresh water should always be available delivered by a water bottle fixed to the side of the cage at a height the hamster can comfortably reach. Pet Shops sell vitamin drops which can be added to water and are beneficial to the hamster.

The hamster should be fed a basic hamster mix each evening and can also be fed supplements. By bringing the time of feeding forward a little each day it is possible to encourage the hamster to waken earlier.

 Most pet shops sell a hamster mix. This mix usually consists of crushed oats, barley, rodent pellets, peanuts, sunflower seeds, maize, dog biscuit and may also include ingredients such as locust bean treats, flaked peas, corn and bird seed.

Hamsters should be fed a basic hamster mix and this should form the main part of their diet. However their diet may be supplemented by other foods but these should be fed as occasional treats. Supplements to a hamster's diet can include:

  • Apple
  • Banana
  • Broccoli
  • Brussel Sprouts - small amounts occasionally
  • Cabbage
  • Carrots
  • Cauliflower leaves and stalks
  • Celery
  • Chicory
  • Clover
  • Corn on the Cob
  • Courgettes
  • Cress
  • Cucumber
  • Dandelion
  • Dock
  • Grapes
  • Groundsel
  • Kale
  • Lettuce - small amounts occasionally
  • Parsley - a good tonic
  • Pear
  • Peas
  • Raspberry Plant leaves - beneficial for diarrhea
  • Spinach
  • Swede
  • Sweet corn
  • Turnip
  • Watercress

Vegetables should be introduced slowly to a hamster's diet as too much can cause diarrhea.

Other tidbits that hamsters enjoy include:
  • Biscuits
  • Boiled Potatoes
  • Bread
  • Breakfast Cereals
  • Cake
  • Cheese
  • Currents and Sultanas
  • Dog Biscuits
  • Egg - scrambled or boiled
  • Mealworms
  • Nuts
  • Toast

You should be careful not to feed too much sweetened food as these could cause the hamster to become fat.

A variety of 'hamster treats' can also be found in pet shops.

Never feed a hamster any of the following:

  • Buttercups
  • Chocolate
  • Garlic
  • Onions
  • Rabbit Mix (containing antibiotic ingredients)
  • Raw Kidney Beans
  • Sweets
  • Toffee
