Ive seen adult mice and there alot bigger than him when it come to width i really dont see him eating it well actually i know hell eat it but its going to take him a while and i just dont feel right giving him that big of a meal im scared its going to hurt him, which i know is stupid to say cuz in the wild they dont pick what size prey they eat, but if something happened to him cuz i fed him something to big i wouldnt forgive myself, ive grown really attached to him over the last 7 months lol
