Hutches should be cleaned out regularly especially in warm weather to prevent lots of flies being attracted – otherwise these can result in an infestation of maggots. Guinea Pigs can easily catch diseases from dirty hutches so make the following points part of your routine:

• Take out any soiled bedding every day
• Once a week
  Remove ALL bedding
  Sweep out soiled bedding
  Rinse the hutch floor and walls with warm water and a disinfectant and wait until dry (put your guinea pig in his run while you do this)
  Replace clean bedding

Bedding is important to keep your guinea pig warm - fresh hay, barley straw, shredded paper, or wood shavings can be used.
