This has been going on for ages - and the photo isn't really clear 'cos cats don't pose:
No kidding. you might see the wisps of steam coming from the condenser boiler steam outlet/exhaust thingy at the side of our house. That daft (or very wise) cat hops onto the six foot high fence whenever one of us has a shower and basks in the warm, moist air from the outlet ........ until her fur is damp and sticks up in spikes :) I'm gonna buy a cat sized towel and hang it on a nail out there, just so she can have a brisk rub down after her sauna session :)
One for Annie's Friday Smile I think! Sigh, we sure do live in a very strange place!
