The cat in question has now moved, but I wasn't using AIBU then and I would like to ask for views in retrospect!
Next door had a cat which kept coming into my garden to poo, wee (which stank) and laze about all day. It also would come into my house if I left a downstairs window open or the patio door. Thus, for two summers with a small baby in the house, I've had to close them when I wasn't in the room. It was also left outside every night in the summer so would start miaowing very loudly outside by baby's window every morning from 5 am onwards to get back in.
Would it have been unreasonable for me to complain about this animal? Is this sort of inconvenience just to be expected if you live next to a cat? Just wondering now... I guess because I'm enjoying my first cat free summer for a while!
