When the temperatures drop, small pets feel it fast — much faster than dogs or cats. Rabbits, guinea pigs, hamsters, gerbils, ferrets, and other pocket pets all rely on us to keep them safe through the cold months. Winter can be tough on their tiny bodies, especially when temperatures swing or drafts sneak into the home.
Use this guide to make sure your small pets stay warm, comfortable, and healthy all winter long.

1. Bring Them Inside (If Possible)
Outdoor hutches might work in mild seasons, but winter weather changes the game. Cold rain, snow, and wind can drop your pet’s body temperature quickly.
- Move hutches or cages into a garage, enclosed porch, mudroom, or indoor area.
- Avoid placing cages in drafty hallways or near doors that constantly open.
2. Add More Bedding — A Lot More
Small pets burrow for warmth. During winter, they need extra materials to nest and hold their body heat.
Good choices include:
- Paper bedding
- Soft hay (for hay-eaters like rabbits and guinea pigs)
- Fleece liners for pets who don’t eat their bedding
Keep it dry. Damp bedding = cold bedding.
3. Use Pet-Safe Heat Sources
Never use heating pads made for humans — they overheat easily.
Instead, look for:
- Pet-safe microwavable heating discs
- Low-wattage safe heat pads designed for small pets
- Insulated hideouts to hold warmth
Always allow a cooler area in the cage so your pet can move off the heat if they get too warm.
4. Protect Their Water Supply
In cold spaces, water bottles and bowls can freeze or get too chilly for proper hydration.
To prevent this:
- Wrap water bottles with insulated covers
- Use bottles labeled “freeze-resistant”
- Check bottles at least twice a day to make sure the ball isn’t stuck
Hydration is just as important in winter as it is in summer.
5. Keep Hutches Dry and Weather-Proof
If your pet must stay outdoors, upgrade their shelter.
- Add wind-blocking panels
- Lift hutches off the ground
- Use waterproof covers
- Stuff hideouts with extra hay
Moisture is the enemy — cold + wet is dangerous for small animals.
6. Watch Their Diet and Weight
Small pets burn more calories trying to stay warm.
- Slightly increase high-quality hay and pellets for hay-eating pets
- Provide healthy fats in moderation (sunflower seeds, certain nuts — species-appropriate only)
- Weigh weekly; sudden weight loss is a red flag
7. Keep Exercise Time Indoors
Cold outdoor playtime isn’t ideal. Instead:
- Create a playpen indoors
- Add tunnels, ramps, chew toys, and safe climbing items
- Rotate enrichment toys to keep them mentally active
This helps prevent stress — and boredom chewing.
8. Check for Respiratory Issues
Cold air can trigger sniffles, wheezing, or labored breathing.
Contact your vet if you notice:
- Wet-sounding breathing
- Loss of appetite
- Lethargy
- Runny nose or eyes
Small pets can decline quickly, so early attention makes all the difference.
9. Keep a Consistent Light Cycle
Shorter daylight hours can affect small animals’ behavior and sleep patterns.
- Keep a regular day/night schedule
- Avoid bright lights at night
- Use soft lighting in their room during early evenings
Routine helps reduce stress.

Winter doesn’t have to be hard on the small pets in your life. A little preparation goes a long way — warmth, dryness, hydration, and proper shelter are the keys to keeping them safe.
