Thanks T.
She is back in isolation at the moment, partly to see if we can stop the dodgy tum (she loves Zia's biscuits, so I might have to introduce those gradually), and partly to help her litter tray issues - she is fine in the bathroom, but when loose in the house, she will head towards the downstairs tray, and if it isn't good enough for her, will use my kitchen floor. I swapped it for a covered tray last night, and followed her, and despite 3 attempts at stopping her (calling her name, clapping and tapping her bum), she still used the floor in front of me - I had already blocked off the first place she used, so it wasn't cos she could smell it. I am hoping when her tum is fine it will all stop, if not, i will just have to put doggy pads there, or rearrange and have two trays.
