Below is a detailed explanation of the space requirements for dwarf hamsters, compiled from information across multiple sources:
I. Basic Space Requirements
Minimum Floor Area
Common domestic standards: At least 40 cm (length) × 30 cm (width), approximately 0.12 square meters.
Advanced recommendations: A 47 cm basic cage (around 0.14 square meters) or a 60 cm basic cage (around 0.36 square meters) is preferable.
International Reference Standards
Germany’s ethical husbandry standards suggest a minimum of 0.29 square meters, with an ideal space of over 0.5 square meters.
II. Height and Multi-Level Designs
Cage height: 20–30 cm is sufficient; priority should be given to floor area rather than the number of levels.
Multi-level cages: They can increase activity space but cannot compensate for insufficient floor area.
III. Effects of Inadequate Space
Behavioral abnormalities: Cage chewing, anxious circling, dehydration, and even self-harm.
Health risks: Lack of exercise leads to obesity and a shortened lifespan.
IV. Special Considerations
Bedding thickness: 5–10 cm of bedding is needed to satisfy their natural digging instinct.
Wheel size: Dwarf hamsters require a wheel with a diameter of at least 17 cm.
Summer setup: Enhance ventilation to avoid high temperatures and stuffiness.
Note: When making a practical choice, consider your living environment and budget, prioritizing expandable, spacious cages.
