What cage for a rat? Height, levels and dimensions to respect
Published by Planète Pets · managing editor: Clément Lacaille · how our guides are written
What cage does a rat need? Unlike the hamster, which needs floor space, the rat is a climber: it needs a tall cage of at least 80 × 50 × 100 cm high for two rats, with several levels connected by ramps. Models such as the Savic Royal Suite or Ferplast Furet XL are the benchmarks of the bedding and habitat category.

What are the minimum dimensions for rats?
Rats live in groups: never adopt a single rat, but at least two same-sex companions. For a duo, aim for 0.4 m³ of usable volume; add roughly 0.1 m³ per additional rat. In practice:
- 2 to 3 rats: 80 × 50 × 100 cm minimum, with 2 or 3 levels.
- 4 to 6 rats: a double cage such as the Royal Suite 95 (95 × 63 × 160 cm), 250 to 350 €.
- Bar spacing: 12 mm maximum for youngsters and females.
- Solid shelves are a must: wire floors cause bumblefoot (pododermatitis).
Why do height and levels matter so much?
A rat spends much of its time climbing, exploring and perching. Levels multiply the usable surface without increasing the footprint on the floor. Watch out for falls, though: never leave more than 40 cm of open drop without an intermediate shelf, especially for older rats.
How should you furnish a rat cage?
The furnishings do half the work: hammocks on every level, tunnels and bridges, ropes, hanging baskets and hideouts. Rearrange the layout every two to three weeks: rats are intelligent and quickly grow bored of a static environment.
What budget should you plan for?
A suitable cage costs 120 to 350 € new, often half that second-hand. It is the main investment, far ahead of the rat’s diet (10 to 15 € per month for a duo). Beware of 60 € budget cages: too small, they breed aggression and stereotypic behaviour.
Frequently asked questions
Is a bird aviary suitable for rats?
Yes, as long as the bar spacing does not exceed 12 mm and you add solid shelves. It is often an affordable, spacious alternative.
Should the levels be closed off at night?
No. Rats are most active at dusk and during the night: that is precisely when they make the most of their cage. Leave full access at all times.
Where should the cage go in the house?
In a calm living area, away from draughts and direct sunlight, and never in a kitchen (greasy fumes) or a garage.
