pregnant mouse

Question
my mouse has just given  birth 3 days ago , is it ok to clean their cage out?

Answer
no it isnt, it could cause her to kill or eat the babies, wait at least 2 weeks to be safe. Good luck, also not sure what bedding you use but please dont use wood shavings as these cause respiratory problems and allergies in rodents, carefresh or newspaper is much better :o)
