The Ruling Class ? <| sep |> Yep so disappointing I was hoping for narrated videos <| sep |> adult mice for a yearling KSB ? are you sure she ' s a year old ? even a female shouldn ' t be big enough to eat adult mice at a year old . how much does she weigh ? you shouldn ' t be removing her to feed in a separate area . always feed in the enclosure . if she doesn ' t eat right away , leave it with her up to 24 hours . get that sand out of there immediately . sand is unsuitable and potentially harmful . shredded aspen or paper rodent bedding such as carefresh are substrates i recommend for KSBs . there should be several inches of substrate for burrowing . my adult female has ~ 10 of carefresh bedding in her tank . 85 is not warm enough . the warm side temperature should be 9095 . what type of thermometer are you using , and where are you measuring the temperature ? you should be using an under tank heater as your primary heat source , and it should be regulated with a thermostat . what type of heat lamp are you using , a light or a ceramic heat emitter ?
