Pussy's Potent Pee Plunges Power Plug to Phut!

Dear George,
The other morning I went to use my large and frequently-emptied litter tray and to my slight surprise found that the back wall had been covered with a sheet of thick blue plastic. Indeed, this blue stuff had been brought down to floor level and my tray was sitting on a larger sheet of it.
I am not bothered by its presence, but I just wondered why it has appeared and wondered if you had any knowledge of such additions to a perfectly normal tray?

Dear Milly,
I am afraid that I have no idea whatsoever as to why your human changed the local décor, so I gave up trying to think about it and sent him a message via the Cat Ethernet. I do not usually bother to ask the inferior species for information: but this was an exception.This is his reply.
Your kind purrs returned.

Dear George,
As if I had dreamt it, I feel the need to write to you to explain a necessary modification to my cat's toilet area. In the small hours of one morning I was awoken by the wind and rain and did what I usually do at such times, turned on the BBC World Service for a news catch-up.
The clock/radio went dead. That week my area had suffered from a lengthy string of power cuts, mostly lasting for just a few minutes or even seconds as the local grid network automatically rerouted itself so as to by-pass a damaged power line. Usually very effective.
However on this occasion I noticed that there were lights on outside. It seemed that only my house was 'out'. So I took it that one of my circuit breakers had tripped. Indeed, the master breaker, as none of my light or power circuits worked.
This was bit of a nuisance for although I have a modern breaker system it is on an outside wall and a previous owner had placed a garden shed in front of it, although with the shed window against the electricity box door. So I had to put clothes on, go outside, reset breaker. Which promptly tripped again. Back inside to find the cause. Which was the power socket on the wall behind Milly’s tray. Where she had done a large pee while standing up. All over the power socket.
I removed the plug and patted the area dry. Went out and reset the breaker, which stayed on. Went back to bed.

Looking at the power socket it was obvious from corrosion of the brass plating and electric contacts that it had all been 'dampened' on a number of occasions. Replacing the socket took but a few minutes and as neither I nor Milly wish to relocate the tray the solution was to use a waterproof cover (wooden floor underlay) over the wall and indeed beneath the tray as a catch-all.
I have since seen Milly do the occasional pee while standing more-or-less upright; she has no problem with her waterworks nor stiffness in her joints, so I put the poor aim down to having other thoughts on her mind, such as "when will it stop raining".
Hope this explains the matter and you can go back to sleep.

Fond strokes to you and all at George Parva.
