Hey my mat just died what I was keeping two containers with 3 month old hatchys on. It's summer in Brisbane ATM. Should I worry I just fed them both this morning. Temps have been okay today. Just worried. I've out some jumper sleeves in there containers to help keep them warmer. But it's not cold ATM should I worry ordered new mats but they won't be here for about a week or two. Help please?
