I forgot to mention that Henry emerged from hibernation at New Year. Whether he was hoping for a share of the remaining Christmas cake he didn’t say.
As soon as I noticed that he was awake he was transferred, complete with his customised winter residence, to my “den” where he will occupy half of my workspace for the next few months until the weather is warm enough for him to go out to the garden. Meanwhile, he has supplementary heat and light to ensure that he gets enough of each until nature takes over, not to mention a five-star room service. The latter supplements my daily exercise by ensuring that I have two or three extra opportunities to climb the stairs daily to deliver Henry’s diet of miscellaneous vegetation.
