Great idea on the bin cage. Do look into colony dynamics. I think I have heard that pairs can pick on each other and they do better in 3's or more? Not sure though.Alright I've decided that if I end up getting mice, I will probably get a pair or 3 females, and I will most likely build my own bin cage they can be a much cheaper option and you can customize it how you want, and provide ample space for the mice. I will probably get females because they are less smelly than males, and they socialize with each other. I will definitely still handle them, but I would worry with a male mouse that it would get lonely. Thanks for the advice and help everyone! Will probably post if I get mice but it may not be until early next year if it happens. If you have any more advice or if there's something you think I need to know, please let me know! The last thing I want is to make any mistakes
I didn't mention scent in my post. My hamster had a cage over 1000sq inches that I thoroughly cleaned once every 4-6 weeks. Never smelled like anything other than paper and wood shavings, except in his bathroom spot which I would spot clean once a week.
Male mice are smelly, I learned that much from my pet store job. For mice in general, it helps to mix wood pellet cat litter (with no additives) into their bedding to help manage scent. Mice are less clean than hamsters and tend to pee all over whereas hamsters will choose one or two bathroom spots, so the wood pellet litter helps combat their bathroom tendencies.
The most important thing for managing scent is having a large cage, I cannot stress this enough. Any animal kept in a home too small is going to dirty it quickly and be very stinky (not to mention the emotional effects of small housing). Get/make a very large cage that can hold lots of bedding. You will clean it less, it will smell less as a result, and the animals will thank you for it.
