A BAT-12 Microprobe digital thermometer and RET-3 mouse rectal probe (Physitemp Instruments, Clifton, NJ, USA) were used to obtain rectal core temperatures to a precision of +/-0.1°C, as previously described
[8 (link)]. Care was taken to measure temperatures ≥2 days after cage bedding changes, and to avoid animal transport stress immediately prior to measurement in order to avoid stress-induced hyperthermia
[23 (link)]. Temperatures were measured between 09:00 and 12:00 each day.
