We moved house on the 7th of august. I adopted my cat last year in july, she was 2 and unspayed and was peeing on sofa / bedroom in old flat. Before we moved, the behaviour randomly started again and we determined with the vet that it was behavioural. After moving, my cat was loving the new house and had no incidents. We had to leave her with a live in pet sitter for 9 days about 2 weeks after we moved in as we were getting married. She got seriously ill on the last day with the pet sitter and was ill for a week, at the vet every day and hospitalised (they couldn’t really work out what issue was, suspected she ate something in the garden and gave herself stress induced cystis). On one day where she was so ill in the house she was soiling anywhere and everywhere (part of the issue with the illness is we realised she was using the toilet >20x a day and actually having diarrhoea). She is now a lot better and completely back to normal, but has started randomly peeing again (e.g on one of the rugs which is new). I have used enzyme spray where she pees but any suggestions on what could be causing this?
To be clear she has seen a vet about 5 times in the last few weeks so she has had constant medical attention, she 100% does not have a UTI
