How to keep your cat warm no matter what temp it is outside

When you head to bed at night or leave the house for the day, you might pop the heat down a couple of notches — it's good to save energy! While putting the temperature to 60 or even 55 degrees Fahrenheit is common, will your cat be comfortable at those lower temps? What are the safe temperature for cats indoors?

Cats love warm and cozy spaces, so before you start fiddling with the thermostat, you need to understand the ideal temps for their health and comfort. In addition to keeping your home warm, there are many ways you can support your cat’s needs throughout the long winter.

What is a safe temperature for cats indoors?

While your cat may have a furry coat, that doesn’t mean he can withstand harsh temperatures. The Rescue Vets explain that felines need to keep their body temperatures at 90 degrees Fahrenheit or higher, or they could develop hypothermia.

As a result, a safe temperature for cats indoors starts at around 50 degrees Fahrenheit. Keep in mind though just because that temperature is safe doesn’t mean your cat will be comfortable. Instead, most cats will find 70 degrees Fahrenheit much more enjoyable.

How can you tell that your cat may be too cold?

Setting your thermostat to 70 degrees Fahrenheit is a good way to ensure your cat stays warm, but it can also be helpful to look for other signs that your cat is too cold and therefore uncomfortable. The Rescue Vets note that when your cat feels cold, you might notice him curling up more tightly than usual or snuggling up next to you more than he typically would.

If your cat has been exposed to particularly low temperatures — for example, if he’s been outside — you might notice additional signs like shivering. Your cat’s paws, ears, and tail could also feel cold to the touch, and his pupils may dilate. A kitty who is way too cold might exhibit slow, shallow breathing and appear weak or lethargic.

Any of these more severe signs mean a trip to the vet is essential. Take your cat to your vet or local emergency clinic to be treated right away.

How warm is too warm for indoor cats?

We've covered the minimum temps but what about the max? It's unlikely that you'll get to these higher numbers in winter, but sometimes a cranked up heating system might do its job too well. Cats can absolutely handle a bit of warmth — you know well how much they love to sun themselves and use your body heat.

However, you don't want your house to get much above 80 degrees Fahrenheit or so for too long. If you live in a place where there are a few particularly hot days, make sure your feline has access to cold water and a cool spot like a tile floor. Lastly, keep your eye out for distress signals lethargy, vomiting, and pale gums. Just like a freezing cold cat, a burning up one might require a vet visit.

What can you do to keep your cat warm and cozy?

The best way to keep your cat warm is to keep your house warm. That said, there are additional techniques you can use to ensure your cat stays cozy all winter long.

Step 1: Check your heating system. You need it to be both accurate and reliable. If you’re going to be away from home for a long period, ask a friend or neighbor to stop in and make sure your heat stays functional.

Step 2: Pay extra attention to his favorite rooms. If you have zoned heating in your home, check the rooms where your cat spends the most time. You can set those to a warmer temp and leave the rest of the house cooler, letting you save energy (and money) while keeping your cat warm and content.

Step 3: Feed him well. Make sure your cat eats a nutritious diet that meets his needs. With the right vitamins, your furry friend will be able to grow a thick winter coat that can help him to stay warm.

Step 4: Find him a nice spot. Give your cat a cozy place to sleep by putting a soft blanket in a warm area of the house, like in a sunny window or by a heater. Always use pet gates or other structures to block off heaters and furnaces, so he doesn't hurt himself.

Step 5: Invest in a pet bed for your cat. To keep your cat extra-warm, consider getting a heated cat bed. These beds can be plugged in and create a continuous source of warmth, which is particularly helpful for older cats or for cats dealing with arthritis.

Most indoor cats do just fine in the winter without extra care, but any cat will appreciate your taking the time to make him an extra warm spot to sleep. Definitely keep an eye on your pet’s behavior during the winter. If you notice him curling up more tightly or seeking out a spot on your lap, you might need to think about turning up the heat in your home or finding other ways to keep your cat warm. An unusually cold cat in a warm house needs to go to the vet for a visit and see if something else is going on.

Why do cats make biscuits? Here’s why your cat kneads
Cat kneading might look strange, but it has a simple explanation

The list of the most adorable things your cat does would have to include purring, meowing, and kneading. But while the first two have obvious causes, you might not fully understand why your kitty makes biscuits. Like so many aspects of pet ownership, you have to look at both the circumstances and your individual animal to get to the bottom of their instincts. The next time you wonder, "Why do cats make biscuits?" — think about their surroundings and nature to figure it out.
What is kneading?
This cat move gets its name because it looks like kneading dough or making biscuits. Generally, cats alternate between their two paws pushing against a soft surface. Not every feline will gravitate to this behavior, and it's a little different for each animal. Be mindful — for some cats, humans are the ideal kneading target. As usual, it all comes down to context, which means you need to pay attention to their knead to determine your cat's inner feelings.

Why do cats make biscuits?
Kneading can have a few different underlying causes, but many of them are about seeking happiness or contentment. However, occasionally, this action indicates something else.
Does your kitty cat exclusively knead around and on you? That might say that they think you're comforting and soft. Careful though, pets can have sharp claws, so if you have a biscuit maker, get them trimmed by the vet.
Most likely, your furry friend picked this up as a baby. Mikel Delgado, a cat behavior consultant, says, "It’s a likely throwback to happy behavior from the days of kittenhood. Kneading is what kittens do when they are nursing to encourage the release of milk from Mom."
When they're extra chill, you might wind up getting pummeled. Remember that your animal's behavior can be controlled with proper training. While it could be instinctual and a source of comfort, you can teach your pet not to knead on you by carefully not rewarding the behavior and redirecting as necessary when they attempt to rub you like dough.
If your animal has not been fixed, making biscuits could be a sign that they want a bun in the oven. This action could also be accompanied by spraying. Similarly, during pregnancy, excessive kneading can indicate that labor is approaching and you're about to have kittens.
Lastly, just like dogs, cats have scent glands in their paws, so they scratch or knead to release their particular aroma. The goal here could be to designate their territory or claim you in particular, especially if there are other beasts in the home.

Cats: We can't live with them, and we definitely can't live without them. Although we could do without the early morning yowling for food, the shedding, and the occasional hairball, our fur babies bring us a sense of joy and wonder that makes every day feel like a holiday.

But we can't help but wonder, "What would my cat's New Year's resolutions be?" While our cats are perfect as they are and most likely have no desire to change, that doesn't mean we can't have a bit of fun imagining what resolutions they might make if they weren't already the flawless and fabulous companions they are today.

A blanket of snow may look stunning, but it makes it difficult for outdoor kitties to find their way home. The potential for accidents also increases due to decreased visibility and the presence of black ice.
