Indoor Exercise for Cats in Winter: How to Keep an Indoor Cat Active and Fit

Why indoor cats slow down in winter

January is the slow season for most house cats. The days are short, the radiator is on, and the sunny spot on the sofa is far more appealing than anything happening on the floor. International Cat Care puts it plainly: without the challenge of hunting and exploring, cats fill their time with the activities that are available to them, mostly sleeping and eating, and that sedentary pattern is linked to obesity and to stress-related bladder disease (feline idiopathic cystitis).

Winter nudges cats in the wrong direction on both sides of the calorie equation. In a four-year study of 38 colony cats fed as much as they wanted, researchers found that food intake was lowest in June through August and highest from October to February; on average the cats ate about 15 percent less in summer than in winter. The same paper cites an earlier study of indoor colony cats in which long-day lighting increased physical activity compared with short-day lighting. More food, less movement, and a body that doesn’t know a bowl refills itself.

The result shows up on the scale. In the Association for Pet Obesity Prevention’s 2022 survey, 61 percent of the 272 cats evaluated by veterinary professionals were classified as overweight or having obesity (28 percent overweight, 33 percent obese), and the figure has barely moved since 2017. Cornell’s Feline Health Center lists osteoarthritis, diabetes mellitus and extra strain on the heart among the conditions excess weight makes worse. If your cat has also started hogging the heating vent, our guide to whether cats get cold covers the warm side of the winter question.

Build up, not out

The cheapest gym you can give an indoor cat is height. Ohio State University’s Indoor Pet Initiative calls a perch “a must have for cats” and defines it generously: anything that lets a cat lie, sit, sleep or look outside from above. Veterinary behaviorist Meghan Herron and Tony Buffington, writing in a continuing-education review for veterinarians, explain why it matters so much. Because the domestic cat evolved as both predator and prey, it naturally climbs for observation and for safety, and indoor cats need perching options throughout the house that are out of reach of people and other animals.

Height is also exercise. The PDSA, the UK veterinary charity, points out that climbing and jumping is a good calorie burner for cats and keeps their joints moving, which is exactly what a cat that can’t patrol a garden in January needs. Cornell’s advice column once put a plump resident cat on a program that was almost entirely architectural: her favorite lounging cushion was moved to a spot she had to climb and jump to reach, and her food was prepared in a room she had to walk to. Those small daily hikes, plus measured meals, worked.

Start with a tall, sturdy cat tree, and put it where the family actually spends its evenings rather than in a spare room. International Cat Care recommends modular or floor-to-ceiling trees with platforms big enough for your cat to lie on comfortably, because a cramped bed goes unused. Set the tree a little away from the wall so your cat can hop on from several angles, and check that it doesn’t wobble; a tree that shifts under a landing cat gets abandoned fast. Our roundups of the best cat trees and best cat scratching posts cover the sturdy ones.

Then look at what you already own. A cleared shelf on a bookcase, the top of a freestanding wardrobe with a chair or table as a halfway step, a chest of drawers under the window: all of these count. International Cat Care suggests a non-slip surface on wooden shelves, which are surprisingly slick under paws, and a route back down that your cat can manage easily. The AAFP guidelines add that perches should be wide and long enough for a full stretch, and that a hammock-style dip or a padded cover helps a cat feel partly hidden, which is what makes a high spot relaxing rather than exposed.

Give the climb a destination. The Indoor Pet Initiative suggests placing a sofa, chair or sturdy table in front of a window, hanging a bird feeder in the yard, and letting the view do the entertaining; a cat may sit on a perch like that for hours, and more than one perch means more than one angle on the action. If you aren’t sure where to put a new perch, watch where your cat already chooses to curl up and fall asleep, then build there. A treat or a favorite toy placed on the perch invites the first visit. Our guide to the best cat window perches has suction-cup and sill-mounted options for renters.

In a multi-cat home, vertical space does double duty. Herron and Buffington note that cats sharing a room like to keep a social distance of roughly one to three meters, horizontally or vertically, and that most housemates use the same perches and hiding spots at different times of day. The AAFP guidelines recommend at least as many safe, single-cat resting places as there are cats, spread around the house, so no one has to compete for the good window. One caution from VCA Animal Hospitals: a cat that naps up high by choice is content, but a cat that lives up high because it’s too frightened to come down is telling you something is wrong on the floor.

Make your cat work for dinner

The second lever is food, and it’s the one most owners can pull tonight. A bowl that is always full asks nothing of a cat. Herron and Buffington write that free access to food removes any chance for a cat to express its predatory instincts, and that depriving cats of that mental and physical work may contribute to obesity. Cornell’s Dr. Carolyn McDaniel names free feeding as a major factor behind feline obesity and recommends distinct, owner-controlled mealtimes instead.

Addressing environmental needs is essential (not optional) for optimum wellbeing of the cat.

AAFP and ISFM Feline Environmental Needs Guidelines, Journal of Feline Medicine and Surgery, 2013

Food puzzles turn a meal back into a hunt. In a 2016 review in the Journal of Feline Medicine and Surgery, Dantas, Delgado, Johnson and Buffington describe the two main types: mobile puzzles shaped like balls, eggs or tubes that a cat rolls with a paw or nose to release kibble, and stationary puzzles with cups and channels that a cat has to fish food out of (the wells also work with wet food). In the case series they report from their own practices, food puzzles introduced alongside other behavior changes were followed by weight loss, less aggression toward people and other cats, less anxiety, an end to attention-seeking and even resolution of litter box avoidance. Start easy and make the puzzle harder only once your cat has it figured out; our best cat puzzle feeders guide ranks the beginner-friendly ones.

You don’t need to buy anything to begin. The AAFP guidelines suggest hiding food in several locations, scatter-feeding dry food, or simply tossing kibbles one at a time for your cat to chase. VCA Animal Hospitals suggests dividing the day’s ration into several small dishes placed around the house so the cat walks for its meals. A veterinary guide to physical-activity programs for cats goes one step further and recommends putting food bowls up on shelves or on a tall cat condo, so every meal involves a jump. Egg cartons, toilet paper tubes and plastic food containers with holes cut in them all make serviceable homemade puzzles.

Play like a hunter, two or three times a day

Play is pretend hunting, and in January it is the only hunting most indoor cats get. VCA Animal Hospitals suggests fitting at least three short play sessions into a cat’s day, ideally timed just before the hours when your cat would normally be active or start pestering you, which for most cats means dusk and the hour before breakfast. Herron and Buffington describe the game cats want: a sequence of stalking, chasing, pouncing and biting, aimed at something they can pick up, toss in the air and pounce on again.

Wand toys are the safest way to run that sequence, because they keep the “prey” away from your hands. Let the feather or ribbon skitter along the floor and up onto furniture, pause it behind a doorway, and let your cat win regularly; a wand that never gets caught is frustrating, not fun. Put wand toys away after each session, since swallowed string is a surgical emergency. Our best cat wand toys guide covers the ones that survive a determined hunter, and if your cat’s hunting is currently aimed at your ankles, this guide explains how to redirect it.

Other formats work too. Herron and Buffington list battery-operated toys that move like prey, a ball inside a box or an empty bathtub (the walls keep the chase going), and catnip toys. They note a general rule among behaviorists for laser pointers: always end the game with a real treat or toy the cat can catch, so the “hunt” has a payoff instead of ending in frustration. Rotate toys every few days to keep them novel; a toy that lives on the floor for a month becomes furniture. Cornell’s Feline Health Center adds that fun toys needn’t be expensive, that paper bags, cardboard boxes and ping-pong balls are tremendously entertaining, and that you should avoid toys with small parts, feathers or string that could come loose and be swallowed. The best cat toys roundup has safe options in each category.

Cardboard boxes, paper bags and other free enrichment

Some of the best winter enrichment comes out of the recycling bin. The AAFP guidelines describe a cardboard box turned on its side as a ready-made safe place, and suggest a perch on top of the box so the cat can hide below or keep watch from above. A box also has real stress science behind it. In a 2014 study at a Dutch animal shelter, researchers randomly gave hiding boxes to 10 of 19 newly arrived cats. By days three and four the cats with boxes scored significantly lower on a standard cat-stress scale, and they reached the calm level that the no-box group took 14 days to hit in about three days.

Novelty itself is enrichment. International Cat Care suggests bringing new items into the home regularly so an unchanging environment doesn’t become so predictable that any change feels threatening: a piece of wood or a stone from the garden, a cat-safe plant, a cardboard box or a paper bag (handles cut off), left somewhere new for your cat to investigate or ignore. The Indoor Pet Initiative files boxes and bags under “novel objects,” one of its five categories of enrichment, alongside food-based games, sensory enrichment such as a fleece-covered perch at a window, social time and positive training.

Scratching counts as a workout too. Herron and Buffington note that cats scratch most after waking from a rest and prefer prominent vertical objects in the areas where they spend time, so a tall sisal post next to the favorite sleeping spot gets used, while one in the garage doesn’t. A full-body stretch on a post several times a day is exactly the kind of low-key movement a winter cat needs, and it saves your sofa; see our guide to stopping cats scratching furniture if that battle is already under way.

A sample winter day for an indoor cat

None of this requires a free afternoon. Here is how it fits around a normal workday in the dark months.

If the night-time zoomies are the problem rather than the lethargy, our guide to cat zoomies and midnight meowing uses the same evening routine from the other direction.

Exercise helps, but calories decide

An honest note before you buy a cat tree the size of a wardrobe. When Cornell veterinarians John Loftus and Joseph Wakshlag reviewed the research on weight loss in cats, they concluded that increasing activity is unlikely to provide a significant benefit in most indoor cats, largely because owners don’t keep it up, while veterinary therapeutic weight-loss diets are convenient and effective. Movement matters for joints, mood and behavior, but the number in the bowl is what moves the number on the scale.

So treat enrichment and portion control as a pair. Weigh or measure every meal, including what goes into puzzles, and use the right food if your vet recommends a diet. Cornell suggests a baby scale at home so you can track a cat’s weight in small steps. A cat that climbs, hunts kibble and plays twice a day but still eats from a bottomless bowl will stay round; a cat that does all of that on a measured ration will not.
