yes, mice can get very sick if you don't keep them healthy
no sick mice should be caged with healthy mice, unless you have the mice checked by a certified vet. Also if the sickness contagious to other animals you should go to the vet and take the sickness taken care of. So if you have a sick mouse DON'T house it with other mice.
mice get sick sick because their digestive system is made to handle plant kinda of stuff not dairy stuff its best not to give them cheese after all
No mice can have bacteria on them that can make you very sick
no i have never heard of them doing that.
You should wash your hands before and after you handle mice. They do carry many diseases.
If they cough on him and they are sick, maybe. Also, if he eats too many of them he could get a tummy ache.
No, but due to the nature of mice to cuddle up when asleep, the other mouse will get sick as well.
Because he was so lonely that he became "sick" to a sense.
no, but it might get sick or feel poorly because they are quite big to eat (I have a dog and he eats mice all the time)
Never feed a mouse caffiene. It can make it sick, or even poison it.
Clean the cage daily.
I think they can go for about 5 or 6 days. One of my Spinnifex mice is really sick from dehydration at the moment though.
