When they are out of the cage our boys like to stretch and roll if they find a sunny spot on the carpet so we've moved the cage so they get sun in about a third of it. I walked past the other day and found Tabasco zonked out in the sunny bit - I promise he is alive! He was like this for ages, he sometimes stretched and rolled onto his other side - guess the new cage position is a good one!
That is adorable. Mine would love to be in the sun, they adore the heatpad and if they are out running and there is a patch of sun coming through they will just lie there. Only problem I have is I have practically no sun coming into the living room. Even I can't stand it. I do feel for my little ones.
