Foraging fun!

I keep switching up their set-up and trying new enrichment such as a play pen and today a dig box!!! Proud to say they crawl on me now and let me lift them, they are really starting to become curious and confident.

Feeder mice vent

I want to start this rant off by saying I am not against feeder mice morally. I've owned reptiles, and am not insufferable to the point I apply human morals to animals a part of the food-chain.

Nonetheless, I think some of these reptile breeders have drifted off the point of no return in the way they treat their mice. I recently got two new fancy mice from a reptile expo, and it took me nearly 15 minutes to find a single mouse that wasn't exhibiting signs of a URI, barbering, extreme stress, or eye infection. What irks me is not only were these mice in horrid conditions, but also that the people were marketing some mice with certain coat-types as 'fancy'. This well-known in my area company was claiming to be breeding show-types. I hate to spoil it, but they were not. I didn't go into a reptile expo expecting to find any type of mouse besides the standard short-coat black, white, or brown coated feeders, but I unfortunately glanced at the three ten gallon tanks they had set up and saw my two little girls following one another around, clearly bonded to the nines.

TW

To paint a picture of the abomination I was looking at, there were three ten gallon aquariums lined up side by side as the company's front row display. This part doesn't seem to crazy without context, but I was at a reptile expo, and you'd think a reptile breeder would show off leucistic ball pythons crammed into deli containers like the rest of the booths before displaying a bunch of stressed out mice front and center. Anyway, I walked up to the table and noticed that in two tanks were strictly feeder-types, and in one other there were both feeders and fancies. I stupidly sent my attention to the tank with fancies within, mostly because all of my girls' coats are the common black, brown, and blondish and I appreciate an uncommon pattern. Once the dead-eyed woman manning the table took off the lid of the tank for me, I immediately watched a male mouse target and vigorously chase another male until I intervened. That's right, apparently a stressed animal being injured by another stressed animal isn't cause for intervention until a customer looks at you crazy for it. The owner took out the aggressor, by the tail(shocker), and placed him in another, I'm sure just as filthy, tank I could not see below the table. The victim male mouse was already injured with multiple cuts and scabs along his ruffled white fur, and he hid in a corner for the rest of my time at the table. The tanks had an inch of soiled aspen, and plastic water bottles that had very clearly become porous with extensive time used, as I could tell by eyesight alone that there was some sort of biological film(algae?) on the sides of the bottles. There were about 15-30 mice per tank, every gender and age mixed together as if intact males don't actively target and often kill younger mice and other intact males.

I wasn't initially going to get any mice from this table, considering that I was only at the expo for taxidermy, and the fact that I have four girls at home who are set up just the way I want them to be. If you can tell where this is going, I caved and purchased two non-pregnant female mice from the table. I payed a 5$ uncharge each for the two seemingly healthy girls because they were technically fancies. How is it even allowed to call a mouse a fancy mouse if you aren't a breeder tracking the genetics of your mice? I'm not complaining about paying an uncharge, just about the audacity. Anyway, I asked a million questions with a straight face about health and potential pregnancy in my two new girls, because if you're marketing some of these mice as pets, ill bother you about them as if they're intended to be such.

The two lady mice are now in quarantine, and the worst of their condition is that one of them has early-stages conjunctivitis in one eye that I'm treating with a generic-brand antibiotic. Surprisingly, they're very social and required literally only one day of bonding to climb up on my hand.

To end this rant, I would like to say that every reptile breeder I've known in my adult life has been passionate about the care of their reptiles. You'd think that the very mice they're feeding these reptiles, which they care so much for, would be shown the same passion as an extension of a reptile's life cycle. It's not like I'm even the most sympathetic person in the world, sometimes animals get eaten and that's the way the world works. But seriously, even as a person who's literally going into a career that requires compartmentalization of the neglect of living beings, I fully understand just how wrong the mice in the reptile industry are being treated.

To ease the inevitably helpless mood we'll have in the comments, I'll attach pictures of my new rescue babies. Give your thoughts, please, because I haven't heard a peep on this thread about the welfare of mice in the reptile industry and would like to know if there's people out there that think like me.

Stella

My sweet baby is taking a liking to her new home. She’s already taking treats from me and being brave enough to sniff my hand. I’m so proud of her!!!

Artemis is still shy, it’ll probably take her longer to get use to me. That’s okay, I’m patient.

Reuniting Mother's with their Babies

Hey mouse people! My sister has 2, female, adult mice and 5 of their female babies. The babies and mommas have been living in separate cages a few feet away (only enough to maybe smell or hear.) The babies are 6 months old now and I was wondering if the two groups could reunite with intros and everything. Considering the large final size of 7. And I do worry about introducing such a big established colony to just the two moms. I feel like the moms would get overwhelmed as they are pretty laid back mice. I will say my sister was not very well informed on mouse care (little clutter, huge open spaces, ect) the first month or so, so both groups are extremely social and act alot less like prey animals than all of my mice have ever acted. I feel like 7 is getting close to the group splitting range, idk. Looking for any thoughts, thanks!

Is this popcorning?

For context, just moved him back into this enclosure after having to separate him and his brother (who has been fostered out now), so hes got free reign finally. Is this him saying yipeee, my own bachelor pad??

Edit: thanks for confirming everyone, I wasn't sure what popcorning is and im so happy Arancini is really excited to have his own pad :)

The girls get blackberry’s from my neighborhood

I freaking love blackberries and they are super invasive where I live so i spend hours running around my neighborhood gathering so many every year and the girls get to share in my harvest. They are extra juicy this year.

how do i stop the midnight barber?

the white mouse (Classic) won’t stop barbering the grey one (Pebble) I’m not sure what is causing her stress? I have 3 mice in a 40 gallon breeder with 8 inches of bedding, a dig box, a 10 inch wheel, two sources of water, climbing opportunities, ample food, foraging opportunities, bridges, ropes, the works. I’ve always had issues with Classic being slightly under stimulated when compared to the other two so I try to take her out more and put in new forms of enrichment but she keeps balding pebble 😭😭 I have an empty 75 gallon, should I switch to a bigger enclosure? Would introducing more mice help even out the dynamic?

Gideon :3

This is my male fancy mouse, Gideon, who was a feeder mouse I was gifted by a teacher after her name didn’t eat him. And with the upcoming of school kicking back up, I’ll be unable to spend as much time with him as I’ve been doing.

I’ve been negotiating getting him a friend for a while now, but I know intact male mice cannot be kept together. And I don’t want babies, I’ve heard my fair share of horror stories with that.

But neutering is so expensive. I want to get him a handful of other friends, but I just don’t have the money right now to do that. Any ideas or other options? I just want the best for Gideon :(

Missing my boys (and hammy)

2026 has been a rough year for me in terms of rodents. I lost a mouse in May and June of this year, as well as a hamster in February.

I’ve been wanting more mice, but am currently on hiatus because I honestly don’t know if I can take another mousey death right now. I already have a middle-aged hamster who I’m not sure will make it to 2027, either.

I thought with each rodent that passes, it would get easier, but the opposite has been true. The last mouse who passed devastated me and I’m still not over it. Was also a pretty traumatic death, and I still haven’t found a way to forgive myself for it.

Has anyone found ways to come to terms with how short their sweet little lives are?

mice sleeping in their old pairs

i’ve just recently introduced my old two girls to my new two girls and they are sharing the same enclosure right now. it would be the start of day three or four and i’ve added their enclosure things piece by piece with the days. right now they have two hides and i’ve noticed them sleeping separated. the two old ones sleeping together and the two newer ones sleeping together. will this disrupt their bonding if they aren’t sleeping ALL together anymore? they were when there was only one hide but now that a second was added last night they are sleeping separated. will they sleep together again once they are more comfortable with each other or should i remove the hide?

normal noises?

one of my girls keeps making this chittering noise and i wanna make sure it's not something to worry about. it's not something she does constantly, only intermittently. i notice it most when i'm near her or handling her, but she could be doing it other times and it's just not loud enough to hear. she sniffs around plenty without making the noise and seems otherwise healthy and energetic. (she makes the noise at 00:11 and 00:57)

Ugh. I can't tell what thpe

I am a wildlife rehabber but struggling to decide if these are house mice or Deer Mice to small to be White footed I believe. But they are almost red like deer mice but don't seem to have enough white coming in.
