hey all, my 3 hogs are currently kept without heat sources. I live in the Uk and it seems alot poeple here use mats for heat, but my higs are kept in my exotic room. the night time temp doesnt drop below 18-20c and they seem fine, active at night when the lights go out and are eating like ....well, like littlehogs! i just wanted some advice from current keepers at to what temps they keep their hogs at and during what periods. in the day time the ambient temps in the room are around 24c, with a night time drop to 18-20c. is this ok?
