I don't think she's in the vents, she could potentially go in but it would be an uncomfortable squeeze and there'd be nothing to hang onto after she penetrated the floor grate, but I am checking them regularly to see if there is evidence of that. I let my little piebald BP loose near her tank a few times and watched where she went to give me some ideas.

Also - I had 3 bowl traps with water, moss, and a dead mouse in the middle in each of the bedrooms. Assuming she followed along the wall closest to her terrarium she probably ended up in the master bedroom and the following night so, two nights ago Kama my boyfriend called out to me and asked if I had touched the mouse. It was still there but it was squished really far into the Moss the Moss was all pushed to one side and the water underneath was exposed. It looked as if she had climbed in and pushed them aside and laid on top of the water and Moss. I have tape on the outside of that door and it doesn't seem like she's left that room. Now it is possible that it was my dog, however he sniff it when I first set it down and I told him no and he's very good about that and very very trained as well as he sniffed a second one and didn't seem interested in it at all so the idea that he would have pushed it all to one side to get to the water is unlikely. I'm not kidding I can leave food on plates on the floor in my house and unless I invite my dog to eat off of it he'll leave it alone he's very very trained.
