Well, well, well. I have discovered something quite exciting now the weather is getting colder. The house next door is quite old - humans call it Victorian - and it has a chimney sticking out of the roof (like most houses around here).
I have never been quite sure what the purpose of this chimney thing is but now I know.
I was sitting on next door's roof yesterday night and gray stuff starts puffing out of the chimney (that bit wasn't so nice) but then the chimney got quite warm. If you sit right next to it you can stay out on the roof for ages. Plus it's a great view up there.
I think I have found my new home away from home.
