I'm with my mum. One of her elderly cats is peeing absolutely everywhere. Her couches have plastic on them, with blankets thrown over. Her carpets are rolled up in corners of the room. There is a strong smell of pee everywhere. Mum has multiple litter trays in every room, and cat flaps installed in every door. Today, puss climbed onto her desk and pissed on the instruction manuals for a new machine she bought. Piss has seeped under the machine too, and partially onto her computer keyboard. It has sunk into the wood of the desk and dripped onto the wooden floor below.
Is there anything we can do? Mum is wretched over it and in total despair.
