Is it safe for cats to be outside in winter? The answer may surprise you

Some cats love being outside, but is it safe for them during winter?

Your cat is more than just a furry roommate — she’s a member of your family. For her own safety, not to mention your peace of mind, we always recommend keeping cats indoors. However, some cats are determined to find their way outdoors no matter what.

While cats can generally withstand both extreme heat and extreme cold without suffering the consequences, veterinarians advise you to remain vigilant once the temperature begins to dip into the 40s. Have you been wondering about the potential dangers for cats outside in winter? You’ve come to the right place. Here’s everything you need to know.

How cold is too cold for cats?

Despite their small size, cats are relatively hardy, resilient critters. In fact, cats are considered apex predators because of their success rate at hunting prey. If humans vanished without a trace, cats would be able to fend for themselves in the wild. That being said, cats are not invulnerable. So, how cold is too cold for cats outside in winter? That depends on the cat in question. It also depends on your cat’s outdoor accommodations. 

Outdoor-only cats are better acclimatized to cold weather than are cats who spend the bulk of their time indoors. However, vets advise against leaving even outdoor cats in the cold when the average daily temperature drops below 45 degrees Fahrenheit. In other words, if the temperature is 42 degrees on Monday and 52 degrees Tuesday through Sunday, your outdoor kitty will be OK. On the other hand, if the temperature reaches only 45 degrees over a seven-day period, it’s time to bring your cat indoors.

How do I keep my cat warm during the winter?

Don’t lose hope if your outdoor cat refuses to come inside during the winter. There are several ways you can keep your stubborn fur baby warm and safe outdoors. Here are a few tips. 

Invest in a shelter

Purchasing a cat house—or building one on your own—will protect your outdoor cat from the elements. Make sure the entrance is small in order to keep out predators and help the shelter retain heat. (Installing a plastic door flap helps, too.) Fleece blankets, straw, and self-warming cat beds are all ideal insulation for your cat’s cozy new place. 

Provide warm food and water

Preventing your cat’s water from freezing over during the winter poses a problem for outdoor cat parents. Placing your cat’s shelter near your home not only will help block out the wind, but also will allow you to use an electric heating bowl to keep your cat’s water from freezing. Cats need more calories during the winter, so we recommend warming a dish of canned food and mixing it in with her kibble. Warming her food will also release its aroma, making her more inclined to consume those much-needed extra calories. 

Bundle up your cat before letting her outside

Winter gear like sweaters and booties are essential if you have an indoor cat who enjoys occasionally roaming the yard. Cats who spend most of their time indoors feel the cold more intensely than cats who live exclusively outdoors, so make sure you bundle up Miss Kitty before allowing her to play in the yard.

What are winter’s dangers to cats?

Freezing temperatures aren’t the only threat to your outdoor fur baby during the winter months. Here are several dangers to cats you’ll need to look out for during wintertime.


Antifreeze is a cold-weather essential if we want our cars to remain functional. Unfortunately, antifreeze is also a toxic substance to cats. A tiny amount of antifreeze can kill a cat, so you’ll want to take precautions when adding antifreeze to your car. Wipe up any droplets immediately and make sure you store antifreeze where curious cats can’t reach it. Remember, not even “pet-safe” antifreeze is completely safe for your cat, though it’s less likely to prove fatal if ingested. Signs of antifreeze poisoning include:

  • vomiting
  • lethargy
  • seizures
  • respiratory distress
  • increased urination

If you suspect that your cat has ingested antifreeze, you should take her to the vet immediately. 


Snow can decrease a driver’s visibility, putting your cat at an increased risk of being hit by an automobile. But that’s not the only danger that cars and trucks pose during the winter. Cats often crawl beneath hoods to stay warm, so you should knock on the hood of your vehicle before you start it. If a cat is hiding beneath the hood, she could be severely injured or killed by the fan belt. 

Ice Melts

Just as antifreeze is necessary to keep our cars running, ice melts help keep roads and sidewalks clear. Unfortunately, cats who stroll across ice melts can suffer a variety of health consequences. If pet-friendly ice melts are used, mild skin irritation and digestive issues can occur. However, ingesting some ice melts can be fatal to your cat, causing symptoms similar to antifreeze consumption.

Cats are stubborn and fiercely independent, but that doesn’t mean they don’t need extra attention during winter. Providing your outdoor kitty with a warm shelter, taking extra precautions when using antifreeze, and checking your car before starting it are all vital to your cat’s wintertime safety. If you can’t keep your cat indoors, at least you can do your part to make her a little safer outdoors.

You love your kitty. Sometimes, that means agreeing to send them in for cat surgery. Whether it’s a standard spay or neuter procedure, necessary dental work, or something more worrisome like removing a cancerous tumor, you’ll want to ensure you give your furry friend some extra TLC post-operation.

Your feline friend may also need you to be patient with them. Cat behavior after surgery can vary from pet to pet, but they may be slightly shyer, lethargic, or easily irritated for a while. The good news is that your cat should go back to normal — and hopefully wind up as an even healthier version of themselves soon. Knowing what to prepare for can ensure your cat feels safe, loved, and comfortable after surgery.

UTIs are a common and pesky condition in humans. It’s short for urinary tract infection. A UTI is an infection of a part of the urinary system, like the bladder, kidneys, or urethra, as the name implies. UTIs can involve painful burning sensations when peeing. They affect about 10 out of 25 women and 3 out of 25 men at least once, according to the Urology Care Foundation.

Cat parents may wonder: What is the rate of urinary tract infections in cats? Unfortunately, it’s not zero. Cats can get UTIs. The good news is that cat health experts don’t commonly see the issue when treating felines. However, it’s still good to think about the urinary tract when approaching your cat’s health.

With their striking rosette coats and low-maintenance grooming needs, Bengal cats are already one of the most desired breeds in the world. Once known as Safari cats, the breed went through a name change in the 1970s to reflect its fascinating heritage. But what is living like a Bengal cat actually like? Are they as feisty as their Asian leopard ancestors?
We'll explore the Bengal cat's personality in depth, covering everything from a brief look into their history, the most common Bengal personality traits, and any breed-specific requirements that may hinder your quest to adopt one of these lovely cats.

Bengal cat history
While some cat breeds, such as the Egyptian Mau, can trace their lineage as far back as 10,000 B.C.E., the Bengal cat is a relative newcomer on the scene. The Bengal cat was first bred deliberately in California in the 1980s, after cat breeder Jean Mill crossed a domestic shorthair (a black tomcat) with an Asian leopard cat. Asian leopard cats, a breed of dainty wildcats hailing from Southeast Asia, are also known as Felis bengalensis -- hence the aforementioned name change from Safari cat to "Bengal cat," -- a nod to this hybrid breed's wild ancestor.
However, there may be another reason for the switch that led to the newly dubbed Bengal cat. When the breed's name was changed in 1974, the man responsible was named William "Bill" Engler -- B. Engler. Some believe he drew inspiration from his own name.
