Is there a humane but very effective way to deter a cat? My mother is 85. Every time her back is turned a cat from a few doors down comes in. It’s been hell for her in the heatwave as she can’t leave any windows open as it gets in. Yesterday she woke up at 5:00 to go to the toilet, got back in bed & it was wet with cat urine. She’d left her window cracked open a tiny amount but the damn cat had wormed its way in. Today she was in the garden with a friend, saw it shoot in through the patio door & by the time she got upstairs it had shot upstairs and sprayed all over her bed & the carpet. It’s also got in through the front window & left a big shit on her carpet.
I went to drop off shopping yesterday and her house was boiling because she can’t ventilate it. She’s too old to be on her hands and knees scrubbing animal faeces off her carpet & urine off her furniture in 30 degrees. She’s tried turning the hose on it when she sees it but it’s not working.
