Hamster sitting while you're away: visits, heat and water

A hamster does not need company the way a rabbit or guinea pig does. PDSA says most hamsters live alone and do not get lonely. That makes a hamster easier to leave for a working day than many pets, and it is why people assume a hamster can manage a weekend on its own. The welfare bodies do not agree. For going away, the RSPCA's advice is to arrange a responsible person to look after your hamster, keep it in its familiar cage with its usual food and avoid moving it unless you must.

The reason is speed. The RSPCA says hamsters have high metabolic rates and can lose condition quickly when they are unwell, and that you should see a vet immediately if you notice signs of illness. Wet tail, the diarrhoea PDSA describes, can cause dehydration and sudden death. A water bottle that leaks onto the bedding, or one whose ball sticks, leaves a small animal with nothing to drink. Nobody notices any of this unless they look.

So Petym's planning guide is a visit every day for a healthy hamster, timed for the evening when it is awake, and a sitter staying in the home for a long trip, a heat wave, or a hamster that is old or unwell.

The RSPCA says to avoid transporting a hamster unless it is necessary, and that small animals not used to travel should not be taken on holiday. A hamster's cage, bedding and food stores are its whole world: it has spent weeks building a nest and hiding food in it. Moving the cage across town in a hot car undoes that and adds heat stress.

If the hamster has to go to a sitter's home, send the whole cage as it is, with its usual food and some used, unsoiled bedding, which the RSPCA suggests for small animals in a new place. The host home should keep it in a quiet room with the door shut against cats and dogs, because hamsters are prey animals.

PDSA advises a steady 18 to 21 °C and warns that a hamster in a hot cage cannot escape the heat and can develop heatstroke. In much of India rooms are far warmer than that from March to June, the months the India Meteorological Department gives for heat waves. A cage left by a window in a shut flat is the most common way this goes wrong.

Before you leave, put the cage in the coolest inner room, away from windows, the kitchen and the balcony, with curtains closed. If the room has a fan on the inverter, show the sitter which switch runs it. Fans move air but do not cool a cage in the sun, so shade comes first. The Animal Welfare Board of India's 2026 heat circular asks owners to give animals shade and fresh water through the hot months.

Cold matters too, which surprises many owners. The RSPCA says domestic hamsters do not have the fat reserves to go without food for long, and below about 20 °C a hamster can go into torpor, a state like hibernation. That can happen in a North Indian winter or in a room where the air conditioning is left running. Leave the AC off in the hamster's room, keep the cage out of the blast of any cooler or heater, and leave extra bedding for burrowing.

• Ask the sitter to check a room thermometer at each visit and include the reading in the daily photo update (Petym's advice).
• Leave a spare water bottle in case the main one leaks or jams.
• If a heat wave is forecast, book a sitter who stays rather than visits.

In the monsoon, bedding absorbs damp and fresh food spoils faster. Petym's advice is for the sitter to remove any wet or soiled bedding and uneaten fresh food at each visit; the RSPCA says not to leave wet or soft food in the cage because it moulds and grows bacteria. Keep the bedding pack sealed so it stays dry, and keep the cage away from windows that let in rain.

For fireworks, the RSPCA advises bringing small pets indoors, giving extra bedding to burrow in and covering any outside cages. At Diwali a hamster is often awake just when the crackers are loudest. Move the cage to an inner room before dusk, add extra bedding so it can dig down, and keep the room dark at the usual time. The sitter should not wake or handle a frightened hamster, and checks the next evening that it is eating.

Before the first booking there is a free meet and greet at your home, in the evening if possible, so the sitter sees the hamster awake, learns where it hides food and how the bottle and lid work. You book and pay through Petym, and the sitter is paid after the booking.

During the booking the sitter follows your plan as you wrote it, logs each visit, feed and medicine, and sends a photo update every day. If something is wrong, the sitter calls you and takes the hamster to the nearest 24-hour vet on the city's list. Every Petym sitter has an identity check with PAN and pet first-aid training before the first booking, and a named 24-hour vet within reach. Sitters who host pets also have a video walk-through of the home by Petym, the housing society's permission and a pet limit.

Petym is not taking bookings yet; it opens city by city once sitters have passed its checks. Its services are built first around dogs and cats. A sitter's visits can cover a hamster too: at the meet and greet, check that the sitter is happy to visit in the evening and knows the warning signs on this page.
