My girlfriend had a stray cat come stay over for a few weeks - during them weeks, the landlord decides to pay the house a visit. They had to quickly hide all the cat's item and throw the cat out for a day.
The cat returned that night after "forced adventuring" for a day.
Never saw the cat again 3 days after...
Anyway, just give your landlord a call, speak to him informally - ask him in terms of scenario / hypothetically. Hopefully he'll be nice and allow so - if now and he wants to visit the place, hide all stuff and throw them cats out.
