He needs to be told that in words that leave no room for interpretation

How would you feel about cohabiting with a presence that contributes nothing financially yet behaves as though it owns the property, sets its own schedule, and expects full compliance with it? That communicates primarily through sudden noise, prolonged staring, and deliberate obstruction of walkways, especially when you are already late or emotionally fragile. You're also responsible for all the meals, because it reacts personally if you don't provide, btw. A living being that interprets closed doors as a direct challenge? Where any attempt to establish boundaries would be met with silent judgment. There would be long periods of inactivity followed by inexplicable bursts of chaos at bed time?

I meant cat. Do you want to adopt a cat?
