The short answer for a fancy rat's sitter bag
A fancy rat staying with a sitter for a week needs his own secure cage or travel cage, familiar-smelling bedding, his usual block-style food with the fresh vegetables he is used to, two water bottles, hammocks and a hide, chew sticks, and written notes covering free-roam time, cagemates, and health watch-outs. Rats are social, routine-loving animals, so the goal of the bag is sameness: same smells, same food, same daily rhythm in a new house.
Food and water: keep the rat's diet boring
Pack measured portions of the exact block or pellet food your fancy rat eats at home, because an abrupt food swap can upset a rat's digestion right when nobody knows his normal droppings. Add a small list of the fresh foods he already gets — a little cooked egg, leafy greens, peas, or banana, in the modest amounts he is used to — and ask the sitter to buy those fresh rather than packing a week of wilting vegetables. Two water bottles matter because ball-valve bottles can stick or leak, and a rat without water for a day is in real trouble; a heavy ceramic water bowl can ride along as backup if he will drink from one. Include a few of his usual treats for handling and training moments, clearly labelled as extras rather than meals.
The cage setup: familiar smells travel with him
If his home cage can move safely, send the rat in it; if not, pack his favourite hammock, one unwashed fleece or bedding handful from home, his usual hide, and a cardboard box or two for shredding. That home scent is not sentimentality — a fancy rat navigates his world largely by smell, and familiar bedding lowers stress in a strange room. Add enough fresh bedding for spot cleans through the week, a small litter tray if he uses one, and wooden chew sticks, because a rat's teeth grow continuously and a bored rat in a new cage will chew the cage itself if nothing better is offered. Tell the sitter to keep the cage away from direct sun, draughts, and rooms with scented candles or sprays, which irritate rat airways.
Handling, free-roam, and cagemate notes
Write down how your fancy rat likes to be picked up — scooped with two hands, never lifted by the tail — and how much out-of-cage time he expects each day in a rat-proofed space with cables and gaps blocked. If he lives with cagemates, they travel together; a week separated from his companions can mean tense reintroductions afterwards, so note the group's dynamics and who tends to boss the food bowl. Note his active hours too: rats liven up at dawn and dusk, and a sitter expecting a sleepy daytime pet may worry unnecessarily at midday stillness.
Health watch-outs to leave in writing
Leave your exotic vet's contact details, your own reachable number, and clear permission for the sitter to seek veterinary care if you cannot be reached. Ask the sitter to watch for repeated sneezing fits, wheezing or clicking sounds when he breathes, a hunched posture with a rough coat, porphyrin's red staining building up around the eyes and nose, or a rat who stops eating and hides away — those changes in a fancy rat warrant a prompt call to the vet rather than waiting for your return. A one-line daily note on appetite and energy helps the sitter spot a slide early.
Handing your sitter a KinsLe Care Pass before you leave puts the feeding list, free-roam routine, and vet details in their hands as one tidy temporary pass, so your rat's week runs on your instructions instead of guesswork.
