A bonded group smells like one family, and that shared scent is the peace treaty. Even a short spell apart can change how gerbils or degus smell and feel to each other, and animals returned as apparent strangers may chase, bite, or fight instead of settling back together. Your briefing therefore protects togetherness at every moment of the stay: feeding, spot checks, full cleaning, and any move between rooms. A sitter who understands that separation is the risk, not a convenience, will plan every task around keeping the group intact.
Put the Never-Separate Rule First
Place the rule at the very top of your written handoff, in plain capital-friendly language a tired sitter cannot skim past: this group lives together, is cleaned together, and travels together, with no animal housed alone, held back in a separate cage, swapped, or introduced to any other animal. Directly under the rule, give the one-line reason about scent and fighting on reintroduction, because a rule with a reason survives a busy evening better than a rule alone. Follow it with the daily basics in group terms: check that every animal is present and eating, refresh water, scatter the usual food, and report immediately if one animal is being chased, bitten, kept from food, or found alone and cold. Before you leave, get the sitter's agreed terms confirmed in writing, covering dates, pay, cleaning duties, vet authorization, and what happens in an emergency, so the arrangement is clear on both sides.
Show the Group Cleaning Method
Demonstrate the full cleaning routine while the sitter watches, then let the sitter repeat the routine under your eye before your trip. Coax or scoop the whole group together into a secure holding carrier with some of their used bedding inside, close and latch the carrier, and set the carrier somewhere quiet and shaded while the cage is emptied, washed, dried, and rebuilt. Only when fresh bedding, hides, wheel, water, and food are back in place does the carrier return to the cage and the group walk out together. Stress that the carrier trip is a group trip every time, even for a quick spot clean, and that no animal stays behind alone in a half-cleaned cage. Point out escape risks as you go: degus chew and climb, gerbils jump and squeeze, and lids, doors, and carrier latches need a deliberate check each time. Agree where the carrier lives during cleaning so it is never placed near a radiator, a window in strong sun, or a household pet who might stare, bark, or paw at animals who cannot move away.
Make Every Animal Identifiable
Togetherness only works if the sitter can tell the individuals apart. Attach a clear photograph of each animal to the handoff with a name, coat markings, size, and any distinguishing feature written beneath, such as a white chin, a nicked ear, or a darker tail tip. Use those photographs during the practice clean, asking the sitter to name each animal going into the carrier and each animal coming back out, so a headcount becomes a named count rather than a guess. Add feeding and health notes per animal under the same photographs: who eats slowly, who guards a corner, who has a vet history, and what normal droppings and activity look like for the group. Ask for a short daily message confirming every named animal has been seen eating and moving normally.
