i was gone for the weekend, and before i left i made sure my 3 mouse girls had plenty of food and water.

for backstory, a couple of months ago i took in someone’s mice because they couldn’t take care of them anymore. when they gave them to me, they were in a tiny 2-5 gallon cage with little to no enrichment. one of them was very overweight, and the previous owner said they kept little food in there to try to put her on a diet.

flash forward to now, i bought the best cage i could find after doing research (i did a LOT of research before taking them in) a prevue model 528, with lots of enrichment. i probably spent $100 on just toys. i feed them a good diet, always have food, water, and hay available.

my mouse girl, rosie, was the one that was very overweight. i didn’t diet her because i know they always need access to food. when i got back tonight, i found her body huddled underneath the bedding. she’s my most loving girl and always comes to me when she hears me. when she didn’t come greet me, i knew something was wrong.

i removed her body, which was stiff. her eyes and mouth were both open. i need help with a potential cause of death. she was about 2, and was very very fat.

her 2 girl mouse friends are left behind, and i’m not sure if i should get another mouse. the 3 were bonded, have always been together. her friends are acting differently, they’re eating and drinking water but not running around as much before.

i don’t know how long they were in there with her dead body, just 2 days ago she was totally fine, eating a little seed out of my hand.

i’m totally blaming myself, worried about the other mice getting sick because i don’t know the cause of death. i removed the bedding where she was laying and planning on doing a deep clean and switching out the bedding, but i need advice on when to do it. i don’t want to stress my two girls out even more by changing up their environment.

also worried about leaving them for 2 days again, but i often spend the weekends at my partners house. i know bringing them with in a small carrier would be stressful to them as well. when i came back they still had food, hay, and water.

any advice and condolences would be appreciated. first time mouse owner, first time a mouse has died, worried 20F :(

My mouse had a litter of babies and it’s my first time ever taking care of a litter. She seems to do all the work, but I’m just curious on the weaning process. When should I be taking the babies out? Can the females continue living with her? And how does that whole process really work? Any advice would be great so I know I’m going at this the right way. Thank you!

I bought this sweet girl from a shop and I noticed one of her eyes were black and has some kinda goop on it I carefully cleaned what I could with some water and a paper towel

She died 3 hours after I noticed her behavior, I made her as comfortable as I could, held and pet her while she took her final breaths. After some tears I made a coffin, buried her by our wildflower garden then made a nice little burial area for her with a handmade cross and gave her a bouquet of flowers… She was only about 5-7 months old.. but I’m glad I got to have her for the time I did even though it was way too short. RIP Nina <3

I just changed from the paper bedding to hemp bedding. I also placed cotton balls throughout their cage so they could use it for their bedding. The two girls (ASF) are sleeping in their house and scampi (the rescue mouse) is behind the house(you can see his little brown butt behind the blue roof). Scampi has really been going around and checking it all out. What are the thoughts on the hemp bedding? I’m just worried they wont be able to make tunnels like they used to but one of the girls, cannoli, would sneeze sometimes with the other bedding so I wanted to use someone more hypoallergenic.

This a picture of one of my mice, she doesn’t have a name nor does my other 5.

They put their head in the hole of this table I have in their cage. I want to understand why they do this.

I have 5 mice, three I got three weeks ago. everyone got along for the most part, but recently everyone has started bullying Moon. At first she only got bullied by her sister, and then one of my older girls started becoming mean toward her. This last night she was getting bullied by everyone, even the smallest white one.

Is there anything I can do to make this better? The weirdest thing is she has always slept with everyone, despite the bullying, but it has gotten so common and with everyone dogpiling her that I felt I had to remove her for her own wellbeing.

They've never drawn blood, but I don't think her constantly being chased and bit is healthy for anyone.

I don’t use Reddit often, so I just found this sub after years of owning mice. Just thought I’d post my little buddy, because the world deserves to know of his greatness. He spent 2.5 years with me and was my best friend ♥️ Truly the best little guy, I always called him a dog in a mouse body. His name was MEL (Em-EE -El or Emielle) and I hope all of you have/ can find a mouse as precious, lovable, and entertaining as him.

Yesterday I got two female mice from my local pet store and they've been doing really good. I was talking to a local breeder who had another female that I wanted because I've read that females are very social. I got the one from the breeder today and introduced them in a container. The new one and one of the females from the pet store fought a little bit but then they calmed down and everything seemed fine. I put them in their cage but ever since they've woken up it's been constant fighting and I don't know what else I can do. Does anyone have any suggestions on what I can do to help them get along?
