It's really interesting to hear what temperature everyone keeps their homes! We have ours around 20 C (6
in the daytime and we used to switch if off completely at night but this is our first winter with Max and he sleeps in his crate in the living room so we worry he will get too cold. So at the moment we keep it between 15 and 16 C (59-61) but we have to turn it down in our bedroom as we get too hot, and that's with a thin summer duvet on!
I still worry that it's too cold for Max sometimes, he burrows in his snuggle sack but I might try and get him some PJs at some point..
