Use a nonlethal trap.
Make sure the mouse isn't a mother. If you capture it, it's babies will die most likely in your house. Whatever you do, don't keep it as a pet. If you like mice, get a couple female mice at a pet store, and give them a big cage with a wheel, and place to sleep.
keep house clean constantly and sweep daily and dont keep food out overnight or you can buy a humane mouse trap (NOT a cruel one) and put peanut butter or cheese in it (peanut butter works best) and when you catch it take it to an open space and then let it run free. It won't find its way back home.
A mouse could bite a rabbit, but they wouldn't bother each other normally.
No they dont harm people
you can leave it because it is really common and it will not harm it!
they dont
dont be silly, buy a mouse trap and put chocolate on it instead of cheese, the chocolate will harm them and they will get trapped. they are attracted to chocolate. for snakes, get a electrnoic snake boom thing which mkaes high noise sounds which kills all snakes.
all of them dont do drugs
Yes, they see it as a little mouse. Something to play and bite. Cats usually play to rough with puppies. Dont trust them alone with your little ones until they are old enough to defend themselves.
It would harm his cheese (money).
Sadly it is very likely.
Yes it is possible that the daddy will harm the babies. He could eat them or injure them especially in the first week of birth. It's smart to remove the male mouse until the babies are at least 3 weeks old.
