Fireworks are among the most dangerous nights of the year for outdoor rabbits and guinea pigs. The bangs arrive without warning, at close range, for hours, and a prey animal who cannot flee will either freeze in terror or throw himself against the hutch trying to escape, which is how backs and legs get broken and how some animals are found dead from shock the next morning. Preparation in the days before, not scrambling as the first rockets go up, is what actually protects them.
Change where and how the hutch sits for the loud nights
The strongest option is relocation: move the hutch and run into a shed, a garage that no car will enter or start, a utility room, or indoors entirely for the peak nights, keeping bonded partners and familiar bedding together so the move itself is the only change. If the hutch must stay outside, muffle it with thick blankets or duvets layered over the top and sides while leaving a clear ventilation gap, because sound must be damped without sealing the animals into stale, overheating air. Pack the sleeping compartment deeply with extra hay and bedding so each rabbit or guinea pig can burrow into the middle of it and feel hidden. Turn the hutch so its solid back faces the likeliest direction of displays, and close nearby curtains and switch on a light or quiet radio in an adjoining shed or room to soften the contrast of flashes and bangs.
Feed early, lock everything, and plan for a breach
Do the evening feed, water check, and lock-up well before dark on display nights, in calm daylight, rather than groping around a run with a torch while explosions start. Check every bolt, latch, and mesh panel with a tug, because a panicking rabbit kicks with serious force and a guinea pig can squeeze through a gap that flexes under pressure; add a second fastening to any door that rattles. Remove anything in the run that a bolting animal could crash into, and make sure identification details and a recent photo for each animal are current before the season starts, not after an escape. If someone else is doing lock-up that night, they need the same checklist, in the same order, because fireworks nights are exactly when a skipped latch happens.
The morning after matters as much as the night
Check the hutch early and quietly: look for injuries from thrashing, a soaked or soiled sleeping area, untouched food, and above all whether everyone is eating, because fright suppresses the gut and a rabbit or guinea pig who refuses breakfast after fireworks is heading toward gut stasis and needs a vet promptly. Some animals stay withdrawn for a day; gentle routine, favourite greens, and quiet company help, but appetite is the line that decides whether waiting is safe. Inspect the hutch and run again in daylight for damage before the next display night, since the season rarely means a single evening. And if the worst happens and a startled animal does get out, speed is everything, so having the alert ready to send to nearby Circle of Love members in KinsLe through the Lost Pet Alert System, with a finder able to message you directly, turns a neighbourhood search into a coordinated one from the first minutes.
