Update!
Madam is still alive and well, and now has the only nesting place with room service. Food seems to be appreciated...
Laptop is back at home, and also alive and well. Clogged up with dust, and this particular type seems to be prone to overheating anyway.
And I found the cat after three days in a shed in the neighbourhood. She's so bloody timid, I bet she kept quiet when it wasn't me she heard walking past. Then she got all upset because she couldn't understand why I wouldn't take her preferred shortcut home across the fence - so she followed me all around the block (5 minutes walk), complaining bitterly. Probably afraid I was about to leave her again.
So not too bad a week after all. Mind you, it isn't over yet...
And on Monday I'll be back at work, after having been off sick since October. Actually not looking forward to it - there's just too much to do in the garden at the moment! Still not fit enough for a full day's work, so hopefully they'll phase me in gradually.
