1. Introduction
Thank you for purchasing the BUCASTSTATE Large Hamster Cage 120cm. This manual provides essential information for the safe and effective use of your new pet enclosure. Please read these instructions carefully before assembly and use, and retain them for future reference.
2. Product Overview
The BUCASTSTATE Large Hamster Cage 120cm (Version 3.0) is designed to provide a spacious and comfortable environment for small animals such as hamsters, gerbils, and hedgehogs. Its design meets international pet cage standards and is recognized by veterinary associations and animal welfare organizations. The cage features a wide and deep layout, ideal for natural behaviors like digging, exploring, and jumping.
- Enhanced Durability: Features reinforced upper beams and shock-absorbing strips to improve stability and reduce noise during pet activity. The high-hardness metal frame offers a premium feel and scratch resistance.
- Improved Ventilation: The top includes two doors, and the number of ventilation holes has been increased from 20 to 42. Side ventilation holes have also been increased from 12 to 20 (compared to the 80cm 2.0 version). This enhances internal air circulation, providing fresher air for your pet.
- Optimized Details & Easy Cleaning: A seamless, waterproof bottom design ensures the cage base is fully washable and can be easily wiped clean with a damp cloth. The waterproof bottom plate prevents urine penetration and lingering odors.
