Before you bring the new mice to home, it is important to make sure you are set up with all the right kit to look after them. And the first thing you should have is the best cage for mice. Mice are cute furry little creatures.
Just like other home pets, mice require cages that are spacious because they love climbing and running around and it should also be easily accessible. Also, mice can easily squeeze through even the smallest of spaces. Due to this, you have to know well about the ideal cage dimension for mice before decide to get the best one.
#1 How big should a mice cage be?
Since mice spend most of their lifetime in the cage so they need ample space that will allow them to move freely about. Besides, they also require some accessories in their cage to live happy. So, the cage must have enough space for all those things to allow the animals to express all their natural behaviours without becoming stressed.
As the basic guide line, when choosing a cage for mice, a cage that is suitable for around 4 rats, will comfortably house around 8 mice. The cage needs a good size bottom space of at least 65 x 45 cm. Besides, mice also love to climb, their cage should not be too low. 40 cm is a good minimum height for a mouse cage.
#2 What is the good size of bar spacing?
Getting the bar spacing right on a cage is crucial to keeping pet mice safe and prevent them from escape. Instead of their age, the weigh is the factor that determine the bar spacing. A difference of 20 g (0.7 oz) in mouse weight can easily make a cage bar spacing suitable or not suitable.
Going to the detail, bar spacing of 6-7 mm is suitable for mice over about 15g. Bar spacing of 9 mm is the standard size for the average adult sized mouse. Bar spacing of 10-12 mm is only suitable for very large mice, and it is better to avoid this as these bars are often weaker and easier for mice to escape from.
#3 How deep should a cage base be?
Remember that there are some cages can offer you the ideal bar spacing but not provide a deep enough base. Mice love burrowing and digging into their substrate and you will want to give them a deep enough base to keep the substrate in the cage and not thrown all over your floor.
Ideally, a cage base should be around 15 cm, but 13-14 cm is still be fine if you cannot find a 15 cm base cage.
