Guinea Pig Cage Setup: The Complete Beginner's Guide

Everything a new guinea pig owner needs: cage size, bedding, hideouts, hay setup, and the mistakes to avoid, plus a first-7-days checklist.

Bigger than you think: cage size

The single most common beginner mistake is a cage that is too small. Most pet-store cages marketed for guinea pigs are nowhere near adequate. For two guinea pigs (and you should always keep at least two, they are herd animals), aim for a minimum of about 7.5 square feet, with 10.5 square feet or more strongly recommended.

C&C (cubes and coroplast) cages are a budget-friendly favorite: you build a spacious, customizable enclosure from storage grids and corrugated plastic for a fraction of the cost of a commercial cage.

Bedding, hideouts, and layout

  • Bedding: paper-based bedding or fleece liners over absorbent pads. Avoid cedar and non-kiln-dried pine, the aromatic oils harm guinea pig respiratory systems.
  • Hay, unlimited: timothy hay available 24/7 is the foundation of the diet and keeps teeth worn down.
  • Hideouts: at least one per pig, plus one extra, so nobody gets trapped or bullied out of shelter.
  • Water: a sipper bottle plus a heavy ceramic bowl for food.
  • Toys: tunnels, chew sticks, and cardboard boxes rotate in for enrichment.

Where to put the cage

Choose a quiet, draft-free spot away from direct sunlight and radiators. Guinea pigs thrive at roughly 65–75°F (18–24°C) and are very sensitive to heat. A family room where they can see and hear you, without constant loud noise, is ideal, because guinea pigs are social and enjoy household activity.

The first 7 days with a new guinea pig

Bringing a guinea pig home is exciting, but the first week sets the tone for your relationship. Keep handling minimal for the first couple of days, speak softly, and offer vegetables from your hand to build trust. Establish the routine, feeding times, spot cleaning, floor time, that your pig will come to expect and enjoy.

The Wheeky Guide app includes a complete first-7-days checklist that walks you through each day: what to set up, when to start handling, what to monitor, and how to tell if your new pig is settling in well. It also covers cage setup step by step, so you can be confident nothing important is missed.

Common setup mistakes to avoid

  • Cages with wire floors, these cause painful foot injuries (bumblefoot)
  • Exercise wheels or balls, guinea pig spines are not built for them and they cause serious injury
  • Keeping a single guinea pig alone, in some countries it is actually illegal to keep just one
  • Scented bedding or air fresheners near the cage
