what cats do at night

Cats are a mystery (that’s part of what we love about them). This cat mystery is even more intriguing at night, when they wander neighborhoods and our homes doing… whatever it is they do.

Why Cats Are Most Active at Night

It’s often said that cats are nocturnal, but that’s not quite accurate. Cats are actually crepuscular, which means they are most active just before the sun rises and just after the sun sets.

Maybe you’ve noticed that your cat seems antsy at night or pounces on your chest to tell you that it’s breakfast time hours before your alarm goes off. This is because, for them, it’s mealtime (and because they can’t pass up an opportunity to deprive you of sleep ; )

Cats are natural hunters that evolved to catch their prey — mice and rats — during the dawn and twilight hours. Just because they now lead cushy lives where their meals are brought to them, it doesn’t remove their instinct to hunt for their model meal (comprised of about 50–60% protein, 30–40% fat, and 10% carbohydrates — a diet that’s too far off these proportions can increase your cat’s risk for obesity, diabetes, and more.

Where Cats Go at Night

It’s natural to wonder where the heck cats go at night. At home, they’re usually sleeping, playing, cuddling, eating, or sleeping some more. But what do they do when they’re off on their own? Turns out, it’s quite a lot.

Researchers at the University of Georgia placed small cameras on 55 cats in the Atlanta area and then studied more than 37 hours of footage to look for trends. Here are a few of the key takeaways.

  • 44% of the cats hunted wildlife. Their main prey were reptiles, small mammals, and invertebrates (things without internal skeletons… think spiders and slugs).
  • Hunting cats captured an average of 2 prey during seven days of roaming.
  • 85% of wildlife captures were witnessed during the warm season (March–November in the Southern U.S.).
  • Younger cats caught more prey-per-hunt than older cats.

Dangers to Cats at Night

During their nightly exploits, the cats in the study also had a habit of putting themselves in danger. Overall, 85% of the cats did at least one thing the researchers deemed a dangerous behavior!The top dangerous behaviors for those cats were:

  • Crossing roads (45%)
  • Encountering strange cats (25%)
  • Eating and drinking substances away from home (25%)
  • Exploring storm drain systems (20%)
  • Entering crawlspaces where they could become trapped (20%).

If you’re curious about your cat’s wanderings or if you want to keep track to avoid losing them if they spend time outdoors, you might consider a GPS collar. In the video below, you can get an idea of what one cat did for about 12 hours during the day when its activity was tracked with a Pawtrack GPS collar.


Note: Preventive Vet recommends that cats not be let outside without direct observation. This is for their own health and safety, as well as the health and safety of other animals in your neighborhood and even you and the other members of your home (cats can pick up zoonotic diseases that they can transfer to humans or bring back fleas and other parasites). If this sounds like a good enough reason to transition your outdoor kitty to an indoor lifestyle, see how to keep an indoor kitty entertained and happy.


Cats' Effect on Wildlife

Even if an outdoor cat manages to steer clear of predators, their own hunting can be quite devastating to local wildlife. Researchers have found that as few as 25 cats in a national park can reduce the local bird population by half! That’s according to the National Park Service, which also notes that domestic cats can deplete the available food source for wild animals.

Animals like coyotes, foxes, skunks, raccoons, and hawks have a harder time finding food in an area where domestic cats have already hunted the available supply. If that’s not concerning enough, the lack of available prey means an outdoor cat will become much more attractive to other large predators.

Why Cats Fight at Night

There are two main reasons that lead to cat fights. As cats prowl neighborhoods and city streets, they will fight when there is competition for food or a mate. In many places, these encounters are more likely because cats’ territories are shrinking as neighborhoods become denser.

According to Dr. Marci Koski, a certified Feline Behavior and Training Professional, studies have shown that cats' home ranges and territories are shrinking as the environment gets more crowded with cats — in other words, more cats in closer proximity equals more encounters and more fights as they compete over resources. And these chance encounters are more likely during the pre-dawn and post-twilight hours when cats are venturing out to hunt (remember how they’re crepuscular?).

Cat-Bite Abscesses From Cat Fights

Unfortunately, cat fights can be quite vicious, resulting in scratches and cat-bite abscesses that can rack up vet bills of several hundred dollars to more than $1,000 and even spread diseases (see more on this below). A cat-bite abscess results in a soft swollen wound under the cat’s skin.

signs of cat bite abscesses

It may be several days before you notice it. Worse still, cat-bite abscesses can pop and ooze the puss within. You might not notice a bite abscess until it begins to swell, but there are additional signs that might indicate a problem.

Signs that could indicate a cat bite abscess:

  • Fever
  • Decreased appetite
  • Lowered energy levels

While some cat bite abscesses may rupture and then heal on their own with some home care, these injuries are best dealt with by your veterinarian.

Other Common Cat Fight Injuries

In addition to bite abscesses, bite wounds are also the primary way of transmitting Feline Immunodeficiency Virus (FIV – a.k.a. “feline AIDS”), as well as Feline Leukemia (FeLV).

Untreated fight wounds can easily become infected. A cat’s mouth carries as many bacteria as a dog’s, but their teeth are better suited to transmit those bacteria, even through minute puncture wounds, according to researchers with the Mayo Clinic.

Cat claws also carry a ton of their own bacteria, which will fester and thrive in the warm moist environment of a fresh wound. In fact, cat scratch fever (the horribly painful disease for humans, not the horribly painful song) is caused by the Bartonella bacteria transferred through a cat’s claws, which is actually transmitted to a cat through fleas.

Unneutered males are far more likely to fight than neutered cats. This is even true of multi-cat households, where unneutered males are more likely to fight with each other as well as spray to mark their territory. Neutering indoor-only cats won’t eliminate fighting, but it should reduce the number of fights.

Sounds Cats Make at Night

Aside from the obvious sound of a cat fight, one of the main times you’re likely to hear a cat is when they want to be heard, like when they’re looking for food or a mate. The video below includes an example of cat mating sounds. You might also enjoy the other videos compiled by Meowsic (think “music” combined with “meow”), a research group that is studying the ways cats communicate with each other — and with us.


Why Cats Yowl at Night

Excessive vocalizing might be due to a variety of factors. If your cat is yowling at night, it might not be cause for immediate concern, but you shouldn’t ignore this behavior either. Here are some of the most likely reasons behind yowling.

  • Old Age: Yowling in older cats might be due to Feline Cognitive Dysfunction Syndrome, otherwise known as feline dementia.

  • Boredom: An indoor cat that doesn’t get many opportunities for exercise or play might yowl excessively because they’re bored.

  • Stress: Sudden changes in a cat’s routine — like the addition of a new baby or a recent move — can stress out a cat and cause them to vocalize.

  • Medical Problems: If you can rule out the other causes of your cat’s yowling, then it’s time for a trip to the vet. Your vet will need to perform an exam and check your cat's blood pressure — and possibly collect blood and urine for testing — to look for underlying medical conditions, such as:

    • High blood pressure (hypertension)
    • Excessive thyroid hormone (hyperthyroidism)
    • Blindness
    • Kidney disease
    • Bladder inflammation
    • And a host of other possible causes

Important Note on Vocalizing: If your cat is vocalizing and straining while using the litter box, get them to the vet immediately! This could be a sign of urinary obstruction, which isn’t just painful and distressing to a cat, but will also be fatal if veterinary care isn’t sought promptly.
