How do I maintain a clean and hygienic guinea pig cage in winter?

Daily Cleaning

In winter, your guinea pig's cage should be spot-cleaned daily to remove waste and uneaten food. This helps prevent the buildup of ammonia, which can be harmful at lower temperatures, especially when the room is below 65°F (18°C).

Use a small brush or paper towel to scoop out waste and food particles from the cage floor. Be sure to check all corners and under the bedding, where waste can accumulate.

• Scoop waste and uneaten food daily
• Check all corners and under bedding
• Use a small brush or paper towel
• Prevent ammonia buildup below 65°F (18°C)

Weekly Refresh

Once a week, you should refresh the cage by removing all bedding and replacing it with fresh hay. This helps control odors and keeps the cage dry, which is especially important in winter when humidity can drop below 40%.

Ensure the new bedding is dry and free of mold or mildew. A good rule of thumb is to use 1–2 cups of bedding per guinea pig, which can help maintain a comfortable humidity level.

• Remove and replace all bedding weekly
• Use 1–2 cups of bedding per guinea pig
• Check for mold or mildew
• Maintain humidity above 40%

Monthly Full Clean

A monthly full clean is essential to maintain a healthy environment for your guinea pig. This involves washing the cage with a mild detergent and rinsing thoroughly to remove any ammonia or urine buildup.

Allow the cage to dry completely before adding new bedding. This can take up to 24 hours, depending on the temperature, and is crucial to prevent respiratory issues in guinea pigs sensitive to cold.

• Wash the cage with mild detergent monthly
• Rinse thoroughly
• Dry completely for 24 hours
• Prevent respiratory issues below 65°F (18°C)

Grooming and Hygiene

Guinea pigs have a self-grooming coat, but you should still check for mats or tangles. Brush their coat with a soft brush once a week to keep it healthy and free of mats.

Trim their nails every 4–6 weeks to prevent overgrowth and injury. Use a guinea pig-specific nail clipper for a safe trim, and be sure to check their teeth for overgrowth, as it can be a common issue in guinea pigs.

• Brush coat once a week
• Trim nails every 4–6 weeks
• Use guinea pig-specific nail clippers
• Check teeth for overgrowth

Monitoring Odour

Odour is a frequency problem, not a product problem. Daily spot-cleaning and weekly bedding refreshes are key to controlling odour. In winter, when humidity is low, these tasks become even more important to prevent ammonia from becoming a concern.

Avoid using strong-smelling cleaning products, as they can be harmful to your guinea pig. Instead, opt for a mild detergent and ensure the cage is well-ventilated after cleaning.

• Daily spot-cleaning
• Weekly bedding refreshes
• Use mild detergent
• Ventilate the cage after cleaning
