Moved house 4 weeks ago, our male cat got out after a week and has gone missing been searching daily for him but no luck. Our female cat seems really settled here, she's always been a nervous cat but seems much more settled here. Came home from work to a smell of cat pee, litter trays are clean so checked the carpets and found a big absolutely soaking wet patch on the living room carpet. Bought a cleaner from pets at home and saturated the area. 2 hours later and she has just walked over and sprayed all up the side of the sofa and on the carpet in a different spot. Any idea why she could be doing this, how to stop it and also the best thing to neutralise the smell? Tia
