How to Keep Chinchillas and Other Rodents Cool in Summer
During summer, room temperatures can rise quickly, making habitats uncomfortable, especially for animals highly sensitive to heat like chinchillas.
To protect them, simply adding a cold object to the cage is not enough: you need to control the environment, reduce heat sources, and offer cool surfaces that the animal can use freely.
In this guide, we'll look at how to keep the habitats of chinchillas, rats, degus, and other small rodents cooler and what accessories can be used as support during the hottest days.
Why are chinchillas particularly sensitive to heat?
Chinchillas have extremely dense fur and are adapted to cool, dry climates. For this reason, they may have more difficulty dissipating heat than other pets.
Rats, degus, rabbits, and other small mammals can also suffer from excessive temperatures, but each species has different needs. Age, health conditions, humidity, ventilation, and room temperature all influence an individual animal's ability to cope with heat.
Therefore, there is no single solution for everyone: it is important to know the needs of your species and consult a veterinarian specializing in exotic animals.
Control temperature and humidity
The first step is to place a thermometer and, if possible, a hygrometer near the habitat.
The perceived temperature for the animal may be different from that measured in another part of the house, especially if the cage is:
✓ near a sun-exposed window;
✓ in a poorly ventilated room;
✓ next to heat-producing appliances;
✓ on an upper floor of the house;
✓ in an area where hot air stagnates.
For chinchillas, a cool and dry environment is generally recommended. The Chicago Exotics Animal Hospital suggests an ideal ambient temperature approximately between 60 and 70 °F (16–21 °C) and notes an increased risk with higher temperatures.
These values are general guidelines and do not replace the advice of a veterinarian who knows the animal.
How to keep the room cool
Cooling accessories can create a cooler area inside the cage, but they cannot lower the temperature of an entire room.
During hot days, it is useful to:
✓ move the habitat to the coolest room in the house;
✓ completely avoid direct sunlight;
✓ close curtains and blinds during the hottest hours;
✓ ventilate the room when the outdoor temperature is lower;
✓ use air conditioning when necessary;
✓ avoid sudden temperature changes;
✓ always provide fresh water;
✓ check the temperature and the animal's behavior multiple times throughout the day.
A fan can promote air circulation in the room, but it should not be pointed directly and continuously at the animal. Furthermore, moving hot air does not cool the environment.
Cooling accessories: what are they really for?
Cooling accessories do not replace ambient temperature control.
Their function is to offer the animal one or more cool areas within the habitat. The rodent must be able to choose freely whether to use them and must always have uncooled surfaces available as well.
Among the most practical solutions are cooling plates, boxes with protected ice packs, and cooling houses.
Aluminum cooling plate
An aluminum plate provides a smooth surface on which the animal can rest during hot days.
Aluminum conducts heat quickly: to the touch, it may feel cooler than wood, fabric, and other materials in the cage. However, it does not produce cold autonomously, and its temperature depends on the environment in which it is used.
The plate is particularly practical because it:
✓ takes up little space;
✓ can be easily moved;
✓ has no accessible plastic parts;
✓ resists bites;
✓ is easy to clean;
✓ can be used as a resting area.
It must be placed on a stable surface and away from direct sunlight.

Marble plate
Marble can also offer a cool and pleasant surface to rest on.
Being a thick and heavy material, it tends to change temperature more slowly than a thin metal plate. However, it is important to check that the slab is stable and that the edges and corners do not have damaged or sharp parts.
Before placing it in the habitat, it must be dry and not excessively cold.

Cooling box with protected ice pack
The Maw's Habitat Cooling Box uses a frozen ice pack inserted into an aluminum drawer.
This way, the ice pack and cooling gel remain separated from the animal. The aluminum gradually transfers the coolness to the external surface, creating an area where the rodent can choose to lie down.
This solution offers several advantages:
✓ the ice pack cannot be chewed directly;
✓ the gel remains out of the animal's reach;
✓ the drawer can be removed to replace the ice pack;
✓ the manual knob prevents accidental opening;
✓ the top surface remains free and usable;
✓ the aluminum structure is durable and washable.
The box must be checked periodically for any condensation buildup.

Cooling house
The cooling house combines a cool surface with a sheltered spot.
It can be particularly appealing to animals that prefer to rest inside a den rather than on an open plate. The structure allows the rodent to choose whether to enter, lean against the surface, or use another part of the cage.
Again, cooling must occur without leaving ice, gel, or cooling materials directly accessible to the animal.

Which solution to choose?
For a simple cool area
The aluminum or marble plate is the most essential solution. It takes up little space and can be easily placed in different parts of the habitat.
To use an ice pack safely
The Cooling Box separates the ice pack from the animal and creates a more intense cool surface compared to a simple plate left at room temperature.
To combine coolness and shelter
The cooling house is suitable for animals seeking a secluded and protected area to rest.
The different solutions can also be used in different parts of the habitat, provided that uncooled areas remain available and the animal can choose where to stay.
What not to do
During hot days, it's important to avoid improvised remedies that could cause thermal shocks or expose the animal to risks.
Do not:
✓ leave the cage in the sun;
✓ place ice directly in contact with the animal;
✓ leave ice packs or cooling gel accessible for chewing;
✓ use surfaces just taken from the freezer in direct contact with the body;
✓ completely wet the chinchilla's fur;
✓ wrap the animal in icy towels;
✓ rely solely on a plate if the room is too hot;
✓ continuously point a fan directly at the cage.
The American Animal Hospital Association recommends avoiding ice and icy water during overheating episodes, as too rapid cooling can be harmful.
How to tell if a rodent is suffering from heat
An animal that suddenly changes its behavior on a hot day should be observed carefully.
Possible signs of discomfort include:
✓ severe lethargy or poor responsiveness;
✓ weakness and difficulty moving;
✓ rapid, labored, or abnormal breathing;
✓ salivation;
✓ loss of balance;
✓ completely stretched out body and unusual behavior;
✓ collapse or unresponsiveness to stimuli.
In chinchillas, lethargy, rapid and shallow breathing, salivation, and weakness are indicated as possible signs of hyperthermia by the Chicago Exotics Animal Hospital.
These symptoms require immediate contact with a veterinarian specializing in exotic animals. A cooling accessory is not a treatment for a possible heatstroke.
In summary
To help chinchillas and other rodents during summer, you need to start with the environment.
The room must remain cool, shaded, and monitored with a thermometer and hygrometer. Plates, boxes, and cooling houses can add cool zones to the habitat but do not replace overall temperature control.
The goal is to offer more choices: a cool surface, a sheltered area, and uncooled areas where the animal can move freely.
Frequently Asked Questions
Is a cooling plate enough to keep a chinchilla cool?
No. The plate offers a surface to rest on, but it does not lower the room temperature. The environment must remain adequately cool.
Can I put an ice pack directly in the cage?
It is preferable to avoid direct access to the ice pack, as it could be chewed and leak gel or liquid. It should be placed in a protected container and checked regularly.
Aluminum or marble, which is better?
Both offer a cool surface. Aluminum is light, thin, and conducts heat quickly; marble is heavier and tends to change temperature more slowly.
Can I put the plate in the freezer?
An excessively cold surface should not be placed immediately in contact with the animal. Always follow the product's specific instructions and avoid sudden temperature changes.
Does a fan cool the chinchilla?
A fan moves air but does not necessarily lower the room temperature. It should not be pointed directly and continuously at the animal.
What should I do if I suspect heatstroke?
Move the animal to a cooler environment and immediately contact a veterinarian specializing in exotic animals. Do not use ice or abrupt cooling methods without veterinary instructions.
