Thanks to you all for the wishes and finger & toe crossing, it worked! On the second visit, at 4.45pm the heating was fixed! (I am still a little paronoid about it though, I keep checking those radiators! lol)
Bob and Ebby were ok, I don`t think they even noticed it was off... I should explain something here. There isn`t any heating in the two bedrooms anyway. Normally, my bedroom is quite cosy because it is not very big and the hot water tank cupboard backs into it, plus there is a radiator in the bathroom which is right next door. The other bedroom (Ebbys room) does get chilly in the wintertime though, (and real hot in the summer morning sun) thats the main reason I changed bedrooms to this smaller one. Obviously, without the heating everywhere became really cold except for the living room and in here with the electric heater on. However neither Bob nor Ebby, yesterday or today, wanted to be in the rooms that I was keeping warm. Oh, no, but guess who is sleeping on my bed right now? You got it, Bosscat Ebby!

Cataholic, looking at the picture now I can see how you might think there is a sleeping bag. But no, it is just one of the quilts and covers left over from when I used to take daily care of my grandaughter when she was a baby/toddler, in fact until she started full time school (she is seven now). I am just a hoarder! I keep the oddest things!
This is a picture I just took (minus kitty) of how Cats Corner is now. Note the pillow has changed places to be in front of her igloo, she likes it that way for some reason!
