It is very common for mice to fight especially males if they are not brothers. The most common reason for mice to start a fight it over food, you could have a bowl filled with sunflower seeds but they will fight over the sunflower seed the other one has. The best way to prevent another fight it to always be adding toys and moving things in the cage. To stop the fighting you can split them up for a week, then re intoduce them in the bathtube or a "neutral" space. Clean the cage and put them together again. Mice that live alone tend to get lonely and will miss their companion.
Only if their in a fight
Mice
Several things could cause it. A decrease in any predator that feeds on mice will cause an increase in mice population because less of them will be eaten by other animals. An increase in the mice food supply could cause an increase in population too, especially if lack of food was the main limiting factor of the mice population. In very rare circumstances, additional mice could be brought in from other parts of the world by humans. There are some non-native fish living in lakes because someone put some in there and they started to breed.
NO!! Mice aren't like little dolls. Even if they show no pain you could injure them greatly or put them deeply in stress. Even a cute bow on their tail could cause problems.
No, but if they are male mice they will fight for dominance
I had mice that did the same thing. They could be struggling for dominance, or one or two of them could simply be aggressive. I took one of the mice back to the Pet Store, no refund but they should take it back. I couldn't listen to them fight all the time.
They get into a fight or accident.
Are there any mice under there?
No, generally diffrent types of mice do not go good together, especially if they are not baby mice. They would probably fight and theres a 50/50 chance they could kill each other. I would strongly recommend keeping them in separate cages, but the cages could be right next to each other. Hope I helped!
I could not find anything that said kerastase oleo caused cancer in mice. It is probably not the best substance for them to eat, but would caused poisoning and not cancer.
no the mouse will be eaten and they fight
Their women, of course they fight.
