🐀 Mice enclosures 🐀 and what they should contain!
🐁 Enclosure size 🐁 80cm by 50cm is the minimum for up to 3-4 mice. (Please note mice are social animals and should not be kept on their own!). Increasing the size of the enclosure to a 100cm by 50cm enclosure for up to 6 mice and larger for more. This is a 120x50x50cm tank with a topper for extra height to add more climbing ropes and hammocks, and currently houses 5 mice (3 boys, 2 girls) with the plan to add two more boys once their hormones have settled from their castrates.
❕It is a common misconception that mice prefer smaller cages, this is not true. They enjoy and need larger enclosures for good welfare. However what do they require is plenty of cover and hiding places to ensure they feel safe, and companionship of other mice.❕
🐀 Wheels 🐀 wheels are a great form of exercise, and many mice love to use them. It is important , however, that they are not too small. I have found that my larger adult mice do well with a 30/32cm wheel (see my previous reel on this), but my younger mice struggle with it. I recommend a 21cm+ as a starting point for baby mice, and then increasing to at least a 25cm+ wheel for adults, and then considering 30/32cm for larger mice. You're aiming for them to easily spin and stop the wheel, but also be straight in their backs when running.
🐁 Substrate, mice love to dig! Ideally they would have a depth of 6inches in some of the enclosure to allow them to dig & tunnel.
🐀 Climbing! Mice love to climb and this is great enrichment and exercise for them. Providing ropes, branches, hammocks etc. They can climb, explore and rest higher up in their enclosure.
🐁 Things to chew such a safe branches, seagrass etc is also good enrichment.
