Cage temps are 75/89. humidity is low at 30%, but very very very difficult to keep up higher due to the glass cage he is in.

probably about 4' long and weighs 1286 grams.

does move around the cage from hot to cold side, and has been active at night quite recently.

up until 1.5 months ago he ate consistently every other week, 3 full mice...
could this be due to the outside temps of aka winter and him being in hibernate mode?
