Yes, if there's something harming them. Like if they get bumblefoot because of there feet hurting after running around in the cave
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.
They do not need to go on annual vet visits like dogs or cats, but when they do get sick they need medical attention, and with some illnesses, they need to get a vet very quickly because they can go downhill very quickly.
No
You need to go to the vet and, see how many kittens there are. If you need them removed do the same go to the vet and they can do ex-rays to find out!!
You need to go to uni of which specialises in vet stuff or science. There are some all of the place you just have to find the one that suites you.
Mice are different so talk to your vet.
Well mice don't really need check up's unless you see or feel that something is wrong. But depending on where you live and the vet you go to, I think about $20-30.
I really hope your joking, but no females, of any species, are spayed. Males, of any species, are nutered. You would only have your female mice spayed if they are around males and you don't want them to have baby mice, but good luck finding a vet to spay your mice.
If you mean a wildlife vet, you need the same amount of schooling that any veterinarian needs, which is to go through vet school.
No go to the vet and ask them what you need to do.
yes. They need to be check if they are well
You need to go to a local vet
