two male feeder mice

Question
i bought a male feeder mouse from a pet store about a week ago and he was not what i expected. he runs anytime i open his cage and will not let me hold him. he'll jump about ten feet and run.

well i read a book from the store on mice and it mentioned that it is better to have two mice so they can groom eachother and cuddle and all that fun stuff so i bought another male mouse.
my 1st male follows the new one around and constantly jumps on him and sniffs his butt. ive also been hearing a lot of squeaking from my 2nd one. im not sure if they are fighting and if i should keep them separate?

the new male is a lot more playful and doesnt mind being held. completely opposite of the 1st.

please help im not sure what to do

Answer
Dear Ashely,
thank you for your question.
It's true that mice are very social and should not be kept alone. Male mice are a problem because they cannot be kept with females (or you will have easily 30 babies in two months) and won't accept another male. You need to separate your mice or they will end up killing each other.
If you can find a vet who will do it, you can neuter one or both of the males and then they can be reintroduced and/or live with females. you need to wait at least 4 weeks before introducing them to females since they may be able to mate one more time during that period and to introduce them to each other, I'd wait at least two months so that they loose their aggressive behavior towards each other. Here are websites that list rodent vets:

Most mice prefer not being held and don't enjoy being petted, but they will take treats from your hand and a group of mice is really fun to watch, even if they don't want thast much to do with their human.

I hope I was of some help to you
