The leak is possible caused by ghosts. Both the upstairs neighbor and I have gotten the landlord to send people to have a look at it. They fixed stuff, it came back. I guess this has been the trend for a very long time. Fixing anything permanently here would basically requires renovictons and we'd rather let the landlord bandaid it than that. This is only my second bird in three years and my cat handled em fine. East coast Canada here so pretty similar climate, less rain more just humid wetness or cold humid wetness of all things unless you put salt on it. Either way I'm actually okay with the place all things considered, the inconvenience is worth it for the cost, it's pretty spacious, has a nice back yard and I'd be paying triple for half the space otherwise
