Can Air Conditioning Make Cats or Dogs Sick?

Working in the air conditioning business, there are certain questions which come up time and time again.

Many of the most common questions come from concerned pet owners, who ask “can cats get sick from air conditioning?” or “can dogs get sick from air conditioning?”.

They’re good questions and, in our latest video, we’ll try and lay out the answer as best as we possibly can.

Why would your pets need air conditioning?

Plenty of people know how much warm air can affect a pet. If your cat or dog has long hair – a particular trait of species from colder climates – you might find that they struggle in the summer months. As Savva explains, even rabbits and other less common animals might struggle in the sweltering heat.

This is especially true when your pet is left at home during the day. While they might seem perfectly fine during most of the year when the temperature starts to rise just a little bit too high, it can leave cats and dogs feeling uncomfortable. So, to stop your pet from overheating and to avoid unwanted trips to the vet, cooling down the house is important.

Because you don’t want to leave a window open with no one at home for security reasons, fully internal air conditioning seems like the natural solution.

As such, a completely internal air conditioning solution is an easy, reliable way to keep your pet happy and healthy when you’re out and about. It doesn’t just cool you down, it cools pets down, too.

But are there any risks?

We’ve seen why people might want to install air conditioning units when thinking about their pets, but that doesn’t help us with the initial question.

When you’re deciding whether air conditioning might be the solution in your home, you want to be extra careful. Asking “can my dogs get sick from air conditioning” isn’t so much a throwaway question as it is an important consideration.

In short, there are no real risks for pets when being left at home with the air conditioning activated. At times when the temperature is high enough that you’d begin to consider cooling the air, your pet likely has other concerns.

Dogs and cats have been on the planet for far longer than our modern technology and they’ve survived harsher conditions than a slightly chilly room.

In asking questions such as “can cats get sick from air conditioning”, it’s often best to think about it in a different context.

There are reasons to be cautious when leaving your air conditioning on, but your pet’s health should always be a primary concern and – most importantly – cats and dogs often appreciate the chance to cool down on a hot day.

Far from getting sick, many pets will enjoy an escape from the scorching temperatures.

How to know when your pet is struggling with the heat

Cats and dogs do tend to get warm in the summer. Just like us, they find stuffy, stagnant rooms with little air flow to be uncomfortable.

Dogs and cats don’t sweat nearly as much like humans, however. Like many mammals, their solution to overheating is to pant, releasing warm air and cooling their bodies.

In the summer, you’ll often find that dogs need more cooling than their feline counterparts. This is due to a variety of reasons, but mostly because they tend to create more heat as a result of their increased muscle activity.

Cats are more likely to simply lay around, while dogs are more active.

In both animals, you’ll find that species with shorter muzzles overheat quicker. Examples would include bulldogs, pugs, and Persian cats. This is because of their reduced ability to pant, so these pets, in particular, can benefit from air conditioning.

To find out more information about whether air conditioning should be left on with pets alone in the home, the American news outlet Mother Jones asked a number of vets and veterinary associations for their expert opinions.

Their conclusions suggested that, far from making pets sick, air conditioning can prevent dogs and cats from getting too warm.

As overheating is far likelier to be dangerous for a cat or dog, it helps to err on the side of caution.

Make sure your furry friend is kept cool and comfortable.

Things to remember

However, that’s not to say that installing air conditioning is a one-stop-shop for anyone with pets. There are a few things you should keep in mind when you’re worried about your pets in the summer months. These include:

  • Leaving the air conditioning on all day can be expensive and can be bad for the environment. Ask our team about our iFeel feature to ensure that the unit is used to its greatest effect. 
  • Humidity can be just as uncomfortable for pets as the heat. Thankfully, our fully internal air conditioning solutions have filters to dehumidify and clean the air which can be very helpful in these situations.
  • It’s important to make sure that your pet always has access to water, especially when the temperature rises.
  • Finally, remember never to leave a pet alone for too long, even if the air conditioning is on.

If you keep these factors in mind, you can make sure that your pet is as comfortable as possible.
