Below is a detailed guide on how often to change bedding for dwarf hamsters, categorized by season and special circumstances, compiled from multiple sources:
I. Regular Replacement Schedules
For Single Hamsters
Basic frequency: Complete bedding changes every 7–10 days. Shorten to 5–7 days in summer, and extend to 10–15 days in winter.
Spot cleaning: Remove soiled, clumped areas daily and clear leftover food every other day.
Adjustments for Multiple Hamsters
For 2 or more hamsters, shorten full changes to every 3–5 days to prevent bacterial growth from accumulated waste.
II. Seasonal Differences
Summer (28°C+)
Prioritize breathable materials like corn cob or wood shavings, paired with absorbent paper pellets at the bottom.
Increase full changes to every 3–4 days, and check for wet spots daily.
Winter (Below 10°C)
Layer paper-based bedding and warm wood shavings to at least 5cm thick.
Extend full changes to 15–20 days, but spot-clean urine stains near nests every 3 days.
III. Special Considerations
Impact of Bedding Type
Wood shavings/paper pellets: Replace every 7–10 days (shorten for dust-sensitive hamsters).
Corn cob: Mandatory changes every 5–7 days (prone to mold).
Health Warning Signs
Replace immediately if there’s a strong odor or hardened clumps.
Frequent sneezing may indicate excessive dust in the bedding.
Behavioral Comfort Tips
Keep 1/3 of old bedding during changes to maintain familiar scents.
Avoid changing bedding in the first 2 weeks of pregnancy or lactation.
Note: In humid southern regions, monitor humidity levels closely. If humidity exceeds 60%, shorten the replacement cycle accordingly.
