A back room, a hide house, and no surprises
A Mini Lop stays calmest through fireworks when the evening is rearranged early: pen set up in a back room by mid-afternoon, hide house in place with its doorway facing a wall, and hay piled deep enough for him to sit inside the pile itself. Mini Lops are compact but dense, and their folded ears do nothing to spare them the noise — sound reaches a lop much as it reaches any rabbit. Drape a cover over one end of the pen so he can pick his own darkness, draw the curtains, and shut the window so flashes and the sharpest cracks stay outside the glass.
Let the Mini Lop hide instead of fetching him out
The instinct to scoop up a frightened Mini Lop works against him. In his own reading of events, being seized during a barrage is the predator moment, and a rabbit who kicks out mid-lift can injure his back. What actually lowers a Mini Lop's fear is an unchanging scene: you in the room at a distance, the radio on at its normal level, and nobody's hands coming over the pen wall. Check on him by eye — ears back and body pressed low is a rabbit coping; the same posture at breakfast time is a different matter.
Routine feeds are a rabbits' all-clear signal
Serve the Mini Lop's pellets and greens at their usual times and refresh his hay just before the display typically starts. Eating is deliberate behaviour for a prey animal, and a lop who keeps pulling hay through the bangs is showing you his fear is manageable. Place water within a short hop of the hide house so he does not have to cross open pen floor to drink. Skip any new treat or food experiment that night — an unfamiliar taste plus a frightening evening muddies the picture if his appetite dips afterwards.
The door discipline that keeps lops found
Mini Lops are house rabbits in many homes, which makes fireworks night a door problem: guests arriving, children drifting, dogs being let out. Keep his room's door closed from dusk, put a note on it if visitors make that necessary, and end any free-roam time before the first display in the neighbourhood, not the first bang you hear. A startled lop freezes before he bolts, so a rabbit found cowering in a hallway should be guided back with a pen panel or a trail of herbs, never chased.
The next morning decides whether to call the vet
A Mini Lop who eats his breakfast, leaves normal droppings, and comes out of the hide house has weathered the night. Ring the vet the same day if he refuses food through the morning, sits hunched with his eyes half closed, grinds his teeth, or has not passed droppings overnight, because a rabbit gut stalled by stress does not restart on patience alone. Note what worked — the room, the cover, the radio — for the next display.
