This live catch mouse trap , is very well built , ( made of metal ) , not cheap plastic ! I bought this for my girlfriend , who does not like to kill anything , and this mouse trap did the job !! We live in a state where the temps get below freezing and although she caught her terror mouse , as she was taking it to the dumpster for disposal , it froze to death before she even got there !! But if you are like her and are squeamish about killing animals , this mouse trap will suite your needs !!
