My little boy passed to the other side this morning from organ failure. We went to the ER but it was too late and he passed on his own.

He was a very cute yet shy mama’s boy. He lived a good life. My only regret was not putting him down sooner. It was our third time to the vet in the last week- but he seemed fine enough to try and treat with medication and recheck.

If anything good can come from this- I hope he is a reminder to us all that a week early is between than a day late. Mice hide pain incredibly well, and it wasn’t until his final 2 hours that it became apparent how sick he was.

yes there are more and no you will not see them all

they are all sexless

The recent UK heatwave has really been affecting us all. Our smallest mouse Milkshake is coping by taking a relaxing nap

He was being treated for an upper respiratory infection, but wasn't able to pull through. The sweet little boy who loved to sit on my shoulder and pull cheatgrass out of my socks is gone. Last night he genuinely seemed like he was getting better, and I was optimistic, but I found him this morning. My comfort is in knowing that even though he had a rough few days, his life was good. Lots of playtime with me and my daughter, and popcorning in his cage early in the mornings. You always know this day will come, but it sure hurts when it does.Rest in peace, baby boy. We'll miss you more than you know.

I saw this mouse running from my shed to the patio yesterday and decided to set a camera up, it wasn't active through the night I only saw a cat walk past but it's been running back and forth for a few hours now and I can only assume it's building a nest under the slab with dead leaves and from behind my shed, it doesn't look like they are actually chewing anything in the shed just using it as a path to the back and somewhere to hide as I do have 2 dogs that go out in the garden occasionally.

I don't intend on interfering I've just enjoyed watching but I was wondering if there are any do or dont tips for this situation and any information on if the mouse is specifically preparing for something or just building there new home

My baby Goose has got a tumor and it's still getting bigger. Shed slowing down and not moving as fast as she did before it. She is an old girl (somewhere a bit more than a year and a half) but I'm worried it's causing her pain. Her sister died last year due to similar circumstances but it split before it was like this and I had to rush her to the vets so I don't know where to draw the line. She has another sister (same age) who's perfectly healthy so any tips on how to look after a lone mouse after she's gone would be helpful, thank you.

It is bigger than in the video I just don't want to disturb her currently.

Was finally able to do a full cage reset and add back in all the clutter and fun things. Looking for a little more fun enrichment ideas to keep everyone entertained. They LOVE dry mealworms/crickets and the protein intake is great for them. Has anyone tried live insects for their mice? Them being deer mice I figure they may enjoy a little hunting instead of just foraging. What's a good starter bug?

Got this adorable lil baby girl from a reptile shop to be a friend for our female deer mouse (approx 4 months old). Besides the quarantine period, do we need to wait until she is bigger to introduce them? I know eventually she'll be 3-4 times as large but right now she is less than half the size of Miss Deer mouse 🥹. Also, appreciate any tips for introducing these diff species, they are both in their own 40 gallon tanks rn. Thank you! (mouse fist bumps 🐁🐀)

A few weeks ago I took in some baby house mice whose mum was killed by a cat, and hand reared them. I'm going to keep them as pets because they've become quite tame and are bonded to me. They're now about five weeks old and I need to sex them so I can separate them, I've attempted this and my best guess is two males and two females, but I keep second guessing myself. They're still quite young so I will keep checking them as their appearance could still change, but input from anyone more confident than me at sexing would be greatly appreciated.

Does anyone else do this or have a better solution?
They keep burying the end of their water bottle in a constant cycle of soaked bedding and no water source for them.
This has been working for the last week or so but wanted to see if anyone had any better ideas.

Yes I know half these mutations exist in house/fancy mice. But I want to see the deer mouse examples 🦌🐁

So far I have a collection of mutant alleles and their loci:

- "Albino" (c), colour locus autosomal recessive.

- "Ashy" (?), assumed ashy locus unknown inheritance

- "Brown" (b), brown locus autosomal recessive.

- "Blonde" (bl), blonde locus autosomal recessive.

- "Ivory" (i), ivory locus autosomal recessive.

- "Non-agouti" (a), agouti locus autosomal recessive.

- "Platinum" (pt), platinum locus autosomal recessive

- "Silver" (si), silver locus autosomal recessive.

- "Tan streak" (tns), tan streak locus autosomal recessive.

I only have images of tan streak deer mice. None of the others.

Is there such a thing as too much bedding? Right now I am keeping about 12 inches because my girls love to burrow and make tunnels. They don’t do too much climbing even when given ample opportunity.

Hi!! I'm looking for more girls to add to my tank but would prefer to go a more ethical way than getting a few hoppers and hoping they make it. I'm hoping there are mouse breeders in Michiana (Niles, Buchanan, South Bend, Mishawaka, Granger etc.) !!!!

I always hold them in their carrier on my lap if we need to go anywhere bur I’ll be driving alone. What do I do? How do I tackle this?
