The Doorway Is the Whole Problem
Guinea pigs on floor time are not trying to escape your house; they are grazing, exploring, and following walls. The danger is timing. A pig ambling along the skirting board reaches the doorway at the exact moment someone opens the door without looking down, and then several risks arrive at once: the door edge itself swinging into a small animal, a foot coming through at pig height, and the open gap leading to stairs, a hallway with a dog, or a front door beyond. A startled pig also bolts in a straight line, and the doorway is usually that line.
So floor-time safety is not really about the pigs. It is about controlling the door and giving a bolting pig somewhere better to run.
Layer Two Barriers, Not One
Choose a room with a door that closes and latches properly, and set a playpen or a line of solid grids inside it as a second boundary around the pigs' area. Either layer alone fails on a real evening — someone forgets and opens the door, or a pig noses a pen panel aside — but the two together mean a mistake has to happen twice in the same minute for a pig to reach a hallway. Place the pen away from the door's swing arc, never directly behind it.
Before the pigs come out, walk the boundary yourself at pig height: gaps under the door a slim pig could squeeze through, cables to chew, gaps behind furniture where a pig can wedge and refuse to come out.
Make the Door Announce Itself
Tell everyone in the house that floor time is happening, and put a note or sign on the outside of the door saying so — memory fails, signs do not. Agree the rule that the door opens only after a knock and a reply, and that nobody carries things through at head height while stepping over pigs they cannot see. Children should sit inside the pen area rather than crossing it repeatedly.
If the household is busy — deliveries, guests, people cooking in and out — that is not a floor-time hour. Pick the quiet stretch instead of relying on vigilance in a crowd.
Give a Bolt a Better Destination
Scatter two or three hides through the floor-time area, including one near the far wall from the door. When a door slams elsewhere in the house or a pig simply spooks, the bolt goes to the nearest dark cover; you want that to be a hide in the middle of the room, not a sprint for the doorway gap. Keep a favourite vegetable for the end of the session so returning to the cage stays a routine the pigs cooperate with, rather than a chase that teaches them to flee from hands near doors.
Count Heads Before the Door Opens Again
Finish every session with a deliberate head count back into the cage before the room returns to normal use — pigs are masters of sitting silently inside a hide while you assume everyone is in. If a pig does slip into the wider house, close exterior doors first, confine dogs, and search along walls and behind appliances at ground level, shaking a familiar food bag.
