In this article, we will discuss some of the best ways to keep rabbits and guinea pigs cool in summer, as well as the dangers of heatstroke and extreme temperatures.

Keep them hydrated!

They can easily become dehydrated during the hottest time of year, so it is important to make sure they have access to plenty of fresh, clean water. Additionally, you can offer your pets vegetables with a high water content, such as cucumbers, zucchini and celery to help them stay hydrated.

Housed outdoors? Provide shade and fresh air

One of the best ways to keep your furkids cool in the summer is to provide them with plenty of shade and fresh air. A shady spot in the yard or a screened-in porch can be the perfect place for your piggie or bunny to get out of the sun and cool off. If you don’t have access to outdoor space, you can place a fan near their cage to create a gentle breeze and to keep the air circulating. Though be careful that it does not get wet due to rain or anything else.

Housed indoors? Use oscillating fans or air conditioning.

If you have air-conditioning, this is another way to keep their body temperature at the ideal temperature. Otherwise, the use of an oscillating fan will help to keep them cool. However, in especially hot summers, this will still not be enough and additional methods will need to be used.

Use a frozen water bottle, ice brick or other water container.

If your pet gets hot, you can lie down a few ice packs (shameless plug: check out our ice bricks with a handmade cover 😜) or frozen water bottles to stay cool. However, make sure to cover them in some sort of cover, such as a tea towel, a cover designed for the item or another safe covering. The reason for this is that, just like humans, the excessive cold can be uncomfortable and can even burn the skin.

Keep them healthy

An obese rabbit or guinea pig is not only at risk of heart complications, arthritis, high blood pressure and other health conditions, but they can also find it difficult to stay cool when it gets hot. So it’s very important to keep your bunny or piggie healthy! You can learn more about what guinea pigs eat and rabbits eat in our following articles:
