I only close the door when I shower or if my brother is visiting. They will sometimes be outside the door when I open it after my shower, mostly because they are waiting for me to feed them.
They can all get in to the basement so it seems like they should all be able to get into each other’s apartments if they wanted to. Though they might want to be careful about it and not let the people know.
Well we don’t know for sure if Sophie has ever actually met Gutter, it is likely that she hasn’t since as far as we know she never goes outside. Wesley on the other had was living with Sophie so he at least had an opportunity to notice, but like Puck said he was pretty much oblivious. His focus seemed to be mostly on cheese and eating trash.
And if Tommy is bringing it to her it will surely be the special cat-safe type because I don’t think Tommy would be getting it out of the people refrigerator.
I think she has grown to car for him, but I think she just sees him as a brother and Tommy seems to be fine with that. Unlike Gutter he doesn’t seem heartbroken by the fact that Sophie has a crush on Wesley.
None of my cats make noise outside the door. I did let PC in the bathroom with me one time when I was taking a shower and she meowed the whole time.
