She only pees outside, never used a litter tray... and now she's taken to peeing on the bathmat. It was very occasionally, if she's been shut through the house, but now it's every bloody day. And tonight - with no bathmat there - she managed to pull the hand towel down and pee on that.
She's old (15/16 we think), but is there anything we can do?? She's had cystitis a few times over the last couple of years but otherwise fairly healthy and sprightly for her age.
Help, I am going demented!
