This year we adopted a Horsfield Tort who is ~10 years old (we think, previous owners had him 7 years and he has 12 rings). He has always lived inside but last year did not hibernate although I think he has done before. He has been living inside with us and I am keen for him to hibernate at least for a few weeks. To this end, we have started the wind down period and he has been living in our conservatory at ~10oC for a couple of weeks, not eating, just mooching gently around in his box. I think he is ready to hibernate* but will take advice on this... However, we live in S Manchester and the temperature is staying warm. Am I correct in thinking that, if it doesn't get cold soon (and drop to ~5oC in the conservatory/anywhere) then Sid just won't go into hibernation?
