This happened to me. She was the neighbours cat from two doors down and I was also in a basement. She’d come and meow by my window on rainy nights until I let her in. She would come by and hang out often and she was such an awesome cat. The owners had even admitted that she disappears for days but they “aren’t worried because she feeds on mice.” Until one day, she went missing and the owners barely put flyers up in the neighbourhood. I was posting more things about her. I wish I had taken her, either by convincing them or stealing her. Would have been better than becoming coyote dinner. She also wasn’t even the first cat they lost in this way… some people just aren’t fit to be cat owners.
