One room at a time

My friend has 3 cats, and she advised me to just let the cats into the living room to start with. I have closed the doors to the other rooms for now.

But considering they are mostly hiding under the sofa, I wonder how long it's gonna take before I can open the other doors.

On the other hand, I can so identify. I don't take to new people easily either. They gonna have to prove themselves.

But when they're ready, I'm here.
