For a new pet-rat setup, choose a spacious, well-ventilated cage designed around the animals’ needs. Blue Cross advises a wire cage and discourages aquarium-style glass housing because ventilation is inadequate. This is a housing-design concern; glass itself is not a poison.
Space and layout
Blue Cross gives a reference size of at least 90 cm long × 60 cm deep × 120 cm high for two to five rats, with larger accommodation for bigger groups. Treat dimensions as one part of the plan, alongside each rat’s size, mobility and access to resources. A cubic-volume calculator alone cannot assess a cage’s suitability.
The RSPCA recommends solid floors, escape-proof construction, hiding places and room for exploration at different heights. Check gaps and fastenings carefully: young rats can squeeze through surprisingly small openings. Arrange climbing furniture to suit the animals’ abilities rather than creating risky falls.
Air, cleanliness and exercise
PDSA links poor airflow and ammonia exposure to breathing problems. Remove soiled material regularly, use suitable low-dust bedding and keep the cage away from draughts and direct sunlight. Give rats supervised exercise in a secure area without access to electrical wires.
The old product list and speculative “coming soon” cage recommendation have been removed. Compare current equipment against these welfare needs rather than relying on an inherited brand endorsement. Start with the rat care guide.
