There are a few ways. Do not let them have babies. Keep the mother and babies away from all other mice.
sometimes they do but only for a short while
No, sometimes they eat the babies if the babies are too big or small, and then they make new ones and start all over again, and repeat the process until they get it right.
Babies can't talk, and they have very little influence over their situation. About the only thing they can do when they want something to change is to cry until an adult figures out what it is that they want.
Female mice will mostly have from 6-12 babies at a time. Some Female might have more or less than that. There really is no right answer to this.
Yes. Generally it is best to keep an adult male mouse by itself because if he is with another male they will fight over territory (sometimes to death) and if he is with a female he will breed with her and you probably don't want babies. I would not recommend keeping female mice alone because there is no reason they can't have a friend. A couple females together will keep each other company... this will keep your mice happy and healthy.
If the runt of the litter is in anyway sick or injured it is possible that the adult females will abandon it, leaving it to die, yes. Chances are that if the runt has been torn apart as (grusome as it may be) it was already dead or it was accidently killed when to females were fighting over who would care for it.
No it will have the human scent on the babies and the adult bird think its we've have taken over its.
to keep women and babies warm, and draped over men's tunics to cover their body while fighting in war
What kind of parent would do that?! But it is for their own sake. You know why? The rat parents eat their babies if they are weak, or are infected. The babies are half awake, so I guess they feel pain. But it is over before they know it. ='( Hope this helped!
they were fighting over land.
Mice are known for eating their young when sick, stressed, or there are too many mice in a cage. If you bother the mother mouse too much she might eat all her babies. When the babies are sick the mother tens to leave it alone to die or kill it. When you have more mice in the cage that will have or has a litter then over crowding is at hand. The mother will also eat the babies if she feels that there is no more space. On rare occasions when having 3 mother mice in a cage and 1 has a litter and the other not, could also lead to eating the babies out of jealousy. I am a breeder and have had 2 females out of 40 in the past 4 months eat the babies. That was do to stress. Try not to vacuum too close to the cages when you have babies. I have had that happen. Mothers eat the babies and the 3 week old will go nuts. I have had a few that died because of the high pitch noise. --Riverbrook Mice will kill and/or allow to die any young that they feel are sick.. If bodies are not removed the mother will eat them in order to keep nest area clean... Kechara saying that some people mistake the mother mouse eating the placenta for eating young this isn't always the case, but they do tend to eat very ill young Adding on its same with hamsters, rats any other rodent They definitely will eat perfectly healthy litters sometimes. I have a female right now who has eaten her last two litters, the last one last night. I'm hoping she'll get over it now that she's older since these were her first 2 litters but I think I'm probably going to have to dispose of her and get a new female if I want babies. They don't get over it a lot of times, they keep on eating the babies from then on once they start.
Timid mice are less likely to be caught by a predator.
