you can start cooling him down...when I have snakes go off feed th is time of the year (normal thing) I put them down for a month or so depending on size. I usually take my breeders off feed late in Oct and put them in the garage in November. Smaller snakes that go off feed for 2-3 weeks this time of the year get put in the garage for a month for a brief brumation cycle. this usually works.
