Mice/Mouse poop


I got my pet mouse about a week and a half ago and I've noticed that his poop has gotten pretty soft since I've had him. It's not diarrhea but it's not solid. I was wondering if it could be that he's on a different food then he was before I got him or if it could be something else. He's quite active so I don't think he's sick. He's been eating Martin's Mouse & Rat Ration but yesterday I switched him to Sunseed Vita Rat, Mouse & Gerbil Formula. I would appreciate any advise or help you could give me!

Thank you!


Hi Emily,

It can indeed be the food.

If it continues, get a probiotic and give him about 1/16 a capsule (divide 4 times) in soy yogurt every 3 days.

You can also get a probiotic product for pets called Bene-bac.

I hope he is better already :)

squeaks n giggles,

I can answer questions about raising mice and caring for them as pets, with knowledge from my 38 years of having fancy mice as pets. I have NO MEDICAL TRAINING and you should take a sick mouse to the vet; but if you simply can't, I will try to help you. I LOVE PHOTOS!!! I ALSO LOVE UPDATES! Let me know how the little tyke is doing later on, for better or worse, especially orphans. It also helps me to help the next person. Please first search first: use 'Natasha Mice Mouse' with whatever else your question includes. Or check out these links: **** YOUR FIRST MOUSE (my video; rough draft): **** TEN VIDEOS ON RAISING ORPHANS: **** SEXING MICE: **** And some GREAT MOUSE INFO SITES:


I have had mice for 40 years (since I was 5!). I raised them when I was a child but now I keep all females, and never fewer than three so that if one dies the others are not devastated, because they have each other.

I run Rats and Mice are Awesome on Facebook. The official name is Rats are Awesome.
