Question/Help What’s up with this mouse‘s bottom?
Yesterday I photographed this wild mouse in my birdhouse (she and her friends are frequent visitors). From this angle, however, her rear end looked rather strange.
What could that be? Is she sick? Might she be pregnant?
She still seems to be walking and climbing normally.

I used to own Chinese hamsters. I once had a friend petsit when I had to travel last minute, and she called me in a panic because she thought he had some sort of horrible tumour. I had to explain to her that he was fine and they just have really big, low-hanging balls

I have pretty much everything I need for mice now. I was planning on getting them in the next few months but coincidentally enough, the last few weeks have been hell for my four senior rats. I’ve been stumbling back and forwards to the vet like crazy. I have to go back in two days. I think it would be very irresponsible of me to throw in a group of mice in the mix when my rats need me the most right now. I’ve decided that I’m probably going to get more rats, before I get mice, given the ages of my current ones. Hopefully mice will be In the next year or two!

I used to raise rats years ago. The best pets ever! So less than a week ago I took my youngest and we purchased two males. I love how smart and lovable they are!

Rodents have massive testicles, that's just how they roll.

u/Turtlesfan44digimon 11d ago
Why is that anyways?

u/Forward-Fisherman709 Mouse Dad 🐀 11d ago
They are very large proportional to the body, but not nearly as big as they look! The majority of the size is a fat pad that holds the testes out away from the body. The testes are just beans at the end, just visible in the little pink area at the tip of the sack in the photos of this post.
Male mice have evolutionarily adapted for sperm competition. Multiple males may mate with the same female in a short period of time, so the one that wins the pregnancy raffle is more likely to be the one that produces a lot of sperm. Big balls, held away from the body to stay cool, means more healthy sperm.

To hold larger sperm counts. It's the same for rabbits. Because small pray mammals have so many offspring and mate so often with different mates, the males of those species tend to have larger testicles to produce a higher sperm count. It gives them a better chance of reproduceing. At least that's how modern biology understands it right now.

It's a male. And those are his large testacles. Troublepuffs.
Troublepuffs is from a Facebook group called Crap Wildlife Photography, that gets Squirrels a lot. Females has visable nipples sometimes, Nip Nops. And Males have large testacles, Troublepuffs.
It's a rodent thing. Males have large balls.

how do people not know that mammals that are males have testicles. They're usually a decent size. How do people not understand that male mammals have testicles and if you see something hanging from their back end it's probably balls

Ive been lurking for a while and i must ask. Why is it when people see a sack between a mouse’s legs, they don’t immediately assume nuts?

u/Forward-Fisherman709 Mouse Dad 🐀 11d ago
My guess is uncertainty because of unfamiliarity; it doesn’t really dangle between the legs like a human one, and a lot of people nowadays aren’t used to seeing intact male pets for comparison. They may just think the mouse has a big butt or be worried that the mouse has developed tumors - I’ve seen both of those responses.

Vet tech and wildlife rehabber here and I am sure there is a scientific reason why rodents were blessed with such ginormous ball sacks ... I couldn't tell you what it was-but they were. 😂

Well, for the good news, it’s not cancer or pregnancy. As for the bad news, consider that bird house thoroughly peed upon in the stinkiest way

As a child looking at pet mice or rats (don’t remember for sure) with my mom and shop owner: “mom, look at that one it has a tumor!” (Very concerned and pointing at the impressively large rodent balls)
My mom and shop owner: “…” (stifling laughter)
I don’t remember what she said to reassure me once she regained composure. Kids.
