Has anyone got any experience of this? We foolishy had him in quite a cold room. He looks pretty dead to me. We moved him into a warm room today, he is by a radiator, but there is no sign of life. He is quite stiff, but his feet aren't stiff though. I've tried touching his whiskers, but there is no movement. My daughter is devastated. I put him on a warm towel, but it hasn't helped
