Enrichment and Nesting for Rats and Gerbils as the Weather Cools

As temperatures drop, rats and gerbils spend more time in their habitats. Here is how to set up safe nesting, digging, and foraging fun to keep them cozy and busy.

When the weather turns cooler and the evenings come earlier, pet rats and gerbils tend to spend more time in their cages and look for ways to stay busy and cozy. October is a great time to refresh their habitat with more enrichment and better nesting. Both species are curious and clever, and a bored rodent is rarely a happy one. Here is how to set up a warm, stimulating space for each.

Rats and gerbils are different

Rats and gerbils both belong in the small-animal family, but they have different needs. Rats are social, climbing, problem-solving animals that love to explore and play with their people. Gerbils are desert burrowers that like to dig and tunnel. Keep the two species in separate habitats, and don't house them together. Within each species, same-sex pairs or groups are usually best, but introductions should be done carefully, so ask your vet or a knowledgeable breeder for advice.

Keep the room comfortable

Rats and gerbils don't cope well with big temperature swings or drafts. Place the cage away from windows, doors, and heating or cooling vents. Choose a spot where the room temperature stays steady and the air is fresh. Cage position also matters for noise, so avoid putting it right next to a TV or in a busy walkway.

Nesting for rats

Rats love to build a nest. Give them soft, safe material they can shred and carry:

  • Plain, unscented paper towels or tissue
  • Strips of plain paper or paper-based bedding
  • Small cardboard boxes they can rearrange
  • A hammock, a fleece liner, or a covered hideout

Avoid fluffy cotton-style nesting material, because the long fibers can wrap around legs and toes. Choose a bedding that is dust-controlled, and skip cedar and pine shavings, since strong-smelling wood oils can irritate the respiratory system. Rats are prone to breathing problems, so clean air matters. Spot-clean daily and change the bedding on a regular schedule.

Enrichment for rats

  • Foraging: Scatter part of the daily food in the bedding or hide it in a cardboard tube so they have to search.
  • Tunnels and hammocks: Rats like layers. Add fabric tunnels, ropes, and platforms at different heights, making sure the levels are not high enough to risk bad falls.
  • Dig box: A shallow box of safe, dust-controlled material gives them an outlet for digging.
  • Chew items: Plain, untreated wood blocks or cardboard help keep teeth and minds busy.
  • Time out of the cage: Supervised play in a safe, rat-proofed room is one of the best forms of enrichment.

Nesting and enrichment for gerbils

Gerbils dig. Give them deep bedding, ideally several inches deep, so they can build tunnels and burrows. Many keepers use paper-based bedding and add hay or plain paper for nest-building. Add cardboard tubes, small boxes, and untreated wood chews, then rearrange them from time to time so the habitat feels new. Gerbils also like a sand bath, using sand sold for small animals, which they roll in to keep their fur in good shape. A solid-surface wheel of an appropriate size is safer than a wire one, which can catch toes and tails.

Food and everyday supplements

A good-quality diet suited to your species is the foundation of good health, with fresh water available at all times. Some owners also like to add a vitamin and mineral supplement. Dr S Tiny Animal Essentials is made for mice, rats, hamsters, gerbils, and other small mammals. It is a mix of vitamins, minerals, essential amino acids, and herbal extracts that goes onto slightly moistened food. The maker's directions call for one pinch per animal per day for mice and hamsters, and two pinches for rats. Always follow the directions on your pack, because the pack has the final word.

This is a nutritional supplement, not a medicine. It does not diagnose, treat or cure illness. Ask your vet first, and see your vet if your pet is unwell, off its food or not acting normal. Follow the directions on your pack.

Watch for changes

Cooler weather is a common time to see sniffles. Contact a vet who treats small animals if you notice:

  • Sneezing, wheezing, or noisy breathing
  • Red or brown staining around the eyes or nose
  • Lumps, weight loss, or a rough coat
  • Lethargy or loss of appetite
  • Any sudden change in behavior

Small animals hide illness well, so don't wait.

Your October checklist

  1. Move the cage away from drafts and vents.
  2. Refresh the bedding, using safe, low-dust material.
  3. Add safe nesting material, tubes, and hideouts.
  4. Rotate toys and hide some of the food for foraging.
  5. Keep an eye on breathing and appetite.

With a few small changes, your rats and gerbils can spend the colder months busy, cozy, and content. For habitats, bedding, hideouts, and enrichment items, visit Pet Megamart, and talk to your vet about anything related to your pet's health.
