I am using these breeder tubs for mice/rats. I have had them for 3 weeks and I have had 3 adult mice escape already. There is plenty of food/water and even a hide. One of the escapees had actually given birth the night before. All 3 escapees were found sitting on top of the cage eating the food like nothing was wrong. None of the bars were out of place and when I called the manufacturer, he said he had never ever heard of any mice escaping when the lid was properly secured. I am just curious if anyone else has had this problem, thanks. http://www.bigappleherp.com/Big-Appl...FRScnAodmkVTLQ
