Mouse Cage Bar Spacing
Another thing you will have to consider when picking out a mouse cage is the distance between the bars. A mouse cages bar spacing is important since mice are well known for their ability to squeeze through tight spaces. A good rule of thumb to follow is that a mouse cage should have a bar spacing of 1/4 to 1/2 of an inch at a maximum.
If you get a cage with a bar spacing that is too wide then you run the risk of your mouse escaping their cage. Another risk associated with widely spaced bars is that your mouse might get caught in them if they try to push their body through and they can’t fit. If that happens your mouse could become injured or even die.
How Many Mice Can Live Together
If you plan on keeping a group of mice (colony) you will have to stick to keeping all females. This is due to the fact that male mice are territorial, and they will fight with other males if they are kept together.
Keeping a male and a female in the same cage won’t have the same risk of conflict, but you will have to deal with the results of them mating. If a female mouse gets pregnant you will have to put the male mouse in a separate cage in order to keep the litter safe and to protect the female from harassment.
If you stick to an all-female colony of mice you can keep 3 to 10 mice in one cage without any problems. Of course, you should still make sure the cage is large enough, and that the cage has hiding spots for each female mouse to take refuge in.
Another thing to consider when keeping multiple mice is cage maintenance. A large group of female mice (colony) will need their cage cleaned on a daily basis. For this reason, it might be easier to keep your mice in separate cages, due to the fact that individual mice usually only need their cages cleaned every three to four days.
How Many Mice in a Litter
In the wild mice can have anywhere from 1 to 32 mice in a litter. There are a number of genetic and environmental factors that go into how many mice are born in one litter. If a female mouse had a mother who gave birth to a large litter she will be more likely to have a large litter herself. The amount of food a female mouse gets can also contribute to the size of her litter.
Domesticated mice tend to have smaller litters since the risk of predation and starvation is lessened in such controlled environments. If you do plan on breeding mice, you should prepare for the maximum litter size so you won’t be taken by surprise. Once the litter is born they will have to stay with their mother until they are fully weaned. After that, you will need to separate the males and female so there won’t be any conflicts.
How Much Does a Mouse Cage Cost
The average cost of a mouse cage is dependent on a number of factors. First, the size of the cage is the largest driver of cost. Second, any included accessories or unique materials will also play a role in the final cost of a mouse cage.
Small Mouse Cage
The price of a small mouse cage can range from $10 to $25. A simple 10 dollar cage in most cases won’t come with any added features, and they will tend to be the smallest option. A 25 dollar cage, on the other hand, will be larger and it might come with an exercise wheel and some other added features.
Large Mouse Cage
A large mouse cage can cost between $30 and $90. A 30 dollar mouse cage will usually have enough space to house a good sized colony of mice, but it won’t come with any extras. A 90 dollar mouse cage will usually have lots of added accessories and in most cases will have the largest internal volume.
