Upgrading Lab-mouse cages
This topic goes close to me bc I work in a lab and have hours every day to think about what I can do for these tiny creatures
Lab mice are kept in these cages by standard:
The minimum legal enrichment (at least in germany) is a nest, something to climb, something to chew, and a way to socialize. This cage has a hut for a nest, the top bars for climbing and the hardened pellets for chewing
In my opinion that's both unfitting and not enough. There's some very simple changes and a lot of bigger/harder changes:
Simple changes:
Using wooden or paper huts. It's commonly believed that mice can't see red, but in reality they will always choose darker colours and more natural materials as hides
lowering the light in one part of the cage, eg simple cage sleeves, lowering the general room light, shading the rack
raising the temperature. Mouse are generally kept at 21 - 24°C, but really prefer 26 - 30°C
scanning the room for ultra sounds
scattering some grains for foraging (this is also perfect for training the mice to make health checks easier)
Other still very simple changes:
adding nesting materials. Mouse prefer paper scraps, paper towels, etc, but there's also cotton squares and wood wool commercially available
adding wood for chewing. Again there's many options ranging from wooden bricks over wooden huts to whole branches
adding a running plate or wheel (I know running plates are said to cause spinal deformity, but in my experience that is a very low chance as opposed to the negative effects no movement has)
adding more bedding so digging is easier
adding tubes, boxes, swings and climbing structures
Changes that get closer to pet keeping:
add diggable bedding for builing nests and tunnels
add more huts. More! Mooore! (seriously mouse love a cluttered space and feel most comfortable walking along walls)
add a second layer (most easy part is just wedging a wooden board in there) and raising the top bars (there's raised cage tops for more height)
adding a maze/labyrinth to allow the mice to compartimentalise their cage/hide from light, sounds, movement, etc
stopping to feed ad libitum. In comercial setting, this can be done with feeding machines, privately this can be done by feeding like any other pet (adding a bowl of fresh food twice a day and removing after an hour or two)
scatter feeding instead of having the food in a rack
adding a digging box
Changes for pet keeping:
Going at least one, better two sizes up with the cages
adding toys
adding more mice to the group (in research most mice are kept in groups of 2 to 5. Mice prefer bigger groups though (plus "two" is a pair, not a group))
adding a big, big layer of bedding (see previous category)
adding toys, including food toys, smell toys, etc
giving food treats like yogurt, comercial treats, varied food, dead or life insects (mice are good hunters!)
feeding grains and similar (if you're unsure about a balanced diet, feeding grains additionally to pellets is totally fine)
adding a bigger wheel or running plate (a wheel is better, if you can provide a good one with appropriate size)
offer a free run time. This could for example be in a bath tub. Lay it out with linen or carpets, fill the tub with toys, treats and cardboard boxes, and offer the mice to go there (eg by builing a stairwell, or by training them "taxi" with a travel box)
spend regular time with them to aclimate them to humans
Changes for a near perfect enclosure:
Upgrate to an aquarium with a grid top
add more climbing options. Like way more!
Put heavier huts on stilts
Add even more tunnels
provide fresh food
change up their enrichment (eg digging box, swimming pool, fresh plants, offer tea additionally to water)
All these images have good and bad items, and imo all enclosures can be adapted to the housed animals needs. I'll try to add credit, but please message me if you have questions about specific images
I was about to add sources but found some great in a single site: here
I also always recommend bin cages as they are cheap and very very customisable. The best example I found is this one

In need of rodent care advice? ask away!
Hi! I have a lot of experience as an owner to hamsters (I've had every captive species as an adult except chinese hamsters), mongolian gerbils, mice, and african pigmy dormice. I have breeding or rescue litter experience with winter white hybrids, campbell's russian dwarf hybrids, african pygmy dormice, mice, and just began breeding syrians. I am well versed in USA minimums and care standards for each of these species, and especially for mice I take a very science oriented care route. Feel free to send an ask if you have questions about care, supplies, diet, health, etc with these species! If you ask about a sick pet, depending on the issue it will likely need vet help, I'm also happy to help you locate a vet nearby that sees the species you have!
While my blog is primarily focused on my special interest of vintage hamster cages, I give up to date advice backed by science and fully with the belief that each individual animal is different, and finding what works for one may not work for another. I also am understanding of the state the US is in, and as long as you are providing at least laboratory minimums I do not think you are abusive. While a 10 gallon tank isn't considered a pet standard ethical for a hamster, scientifically it IS ethical, and if you are unable to provide larger for some reason (parents won't let you, cannot afford a larger enclosure atm, etc) it is important to instead offer as much enrichment as possible. I will always educate on what is recommended by pet keepers, but will also give situation specific advice as long as you give me as much info to work with as possible!
Please remain civil in reply to any ask where an owner is unable to provide all that the pet community wants to require, driving owners further away from the community only makes it harder to educate.

"i wanna see something other than the same edgy horror stuff when a beloved character becomes public domai-"
FUCKING MAKE IT, THEN.
the literal only difference between you and those horror directors who took mickey and winnie the pooh and made them into the horror you hate so much is that they made something and you didn't.
MAKE the romcom. MAKE the deep and existential meta horror you want to see. MAKE something cozy and child friendly. MAKE MAKE MAKE MAKE MAKE
don't just sit there and bemoan the things you don't want to see! MAKE THE THINGS YOU DO WANT TO SEE. BECAUSE NOW WE CAN MAKE ANYTHING. THAT'S THE FUCKING POINT!
YOU DON'T NEED PERMISSION. YOU DON'T NEED TO BE SOMETHING FIRST. JUST MAKE WHAT YOU WANT TO SEE.
YOU CAN'T STOP AN ARTIST FROM TAKING A CHILD FRIENDLY THING AND MAKING IT INTO HORROR. THE LITERAL ONLY PERSON YOU CAN STOP, AND ARE STOPPING, IS YOURSELF.
DON'T FUCKING WAIT FOR SOMEONE ELSE TO MAKE IT FOR YOU. PICK UP A DAMNED PENCIL/KEYBOARD/WHATEVER AND MAKE THAT THING YOU WANT TO SEE, GOD DAMMIT!!!

just kinda a thing i wanted to say since ik i have younger artists following me (its applicable to everyone really, but very important to form care habits as early as possible)
i read about others artists experiencing pain from overworking and i always thought to myself, i wouldnt let that happen to me, im real young, i still have time before i have to worry about really damaging my body
but your body really doesnt care, if you push yourself, if you ignore the pain, its going to fuck you up. maybe for the rest of your life
please god take care of yourself when you draw, write, game, literally anything. stretch your wrists, fingers, dont keep your elbow in a locked a position for too long, especially dont lean on your elbows. get up around every 45 minutes, drink water, eat food, use the bathroom, stretch your whole body and your hands again. walk outside and let your eyes readjust
your body is trying to communicate with you for a reason when you start hurting, please listen to it, be kind to yourself, you deserve it
