Indoor cat activity through play, toys and climbing space

Indoor living is one of the clearest early risk factors for an overweight cat. In the Bristol Cats study, which followed nearly a thousand UK kittens, cats with restricted or no outdoor access were more likely to be overweight or obese by about 13 months of age, as were cats eating mainly dry food. The authors advise keeping a close eye on food amounts, exercise opportunities and body condition in such cats. An indoor cat still has the urge to stalk, chase and pounce; it simply has fewer chances to use it.

What indoor cats are missing

The AAFP and ISFM feline environmental needs guidelines describe five needs that apply to every pet cat, indoors or out. A cat needs a safe place to retreat to, and key resources (food, water, litter trays, scratching posts, resting spots and high perches) in several separate locations. It needs chances to play and act out predatory behavior. Contact with people should be positive, consistent and predictable. And the home should respect the cat's sense of smell. The panel links stress from unmet needs to illness, including idiopathic cystitis, and to unwanted behavior.

For an indoor cat, play is the need that takes the most deliberate effort, and even a little of it has measurable effects. In a UK trial with cats that had outdoor access, households that added 5 to 10 minutes of daily object play saw the number of animals their cats caught and brought home fall by 25%, which suggests that play meets part of the motivation to hunt.

A daily play routine

There is no evidence-based minimum for play. The predation trial used 5 to 10 minutes a day, and two short sessions fitted around the household's routine are a practical place to begin, with more for young or very active cats. Many cats are livelier in the early morning and evening, which makes those good times to try.

A session works best when it follows the shape of a hunt. The AAFP and ISFM panel suggests moving a wand toy with feathers or fur so that it behaves like prey: swooping through the air like a bird, or darting away in straight lines like a mouse. The panel also advises letting the cat catch the toy to simulate a capture and giving a treat after play. A workable session starts slowly so the cat can watch and stalk, speeds up for the chase, and lets the cat make several catches. Hands and feet should never be the toy, since that risks injury to both cat and person.

In homes with more than one cat, it helps to play with each cat at a separate time and keeping toys in separate places, to avoid competition and social tension.

Toys and why rotation works

Cats lose interest in a familiar toy quickly. The guidelines recommend using toys on a rotating basis to prevent habituation and boredom: keep a few out, put the rest away, and swap them regularly so that old toys feel new again. Different toys suit different parts of the hunt.

• Wand and feather toys for interactive stalking and chasing, put away after each session so they stay interesting and nobody chews the string.
• Small balls and springs for batting and chasing alone.
• Large soft toys and kickers that a cat can grab, rake with its back legs and bite.
• Toys that hold food or hide in boxes, which add searching to the game.

Laser pointers are popular, but they never let the cat catch anything. In a survey of 618 cat owners, the more often a cat played with a laser, the more likely its owner was to report repetitive behaviors such as chasing lights or shadows, staring at reflections and fixating on a particular toy. The study shows an association, not proof that lasers cause the problem. Still, a wand toy that can actually be caught is the better default. If a laser is used at all, finishing on a physical toy lets the cat complete the catch.

Climbing and high resting places

Height gives a cat more usable territory in the same floor area and a place to watch the room from. Raised perches are one of the core resources in the environmental needs framework, and they should be wide and long enough for the cat to stretch out fully, ideally with a slight dip that helps it feel hidden.

• A sturdy cat tree near a window, heavy or anchored enough not to wobble when the cat jumps on it.
• Wall shelves in a staircase pattern, which add climbing routes without taking floor space.
• A window perch, which gives the cat something to watch. A bird feeder outside adds interest, as long as it is placed where visiting birds are not at risk from other cats.
• Hiding places such as a cardboard box on its side, which many cats use as a safe retreat.

In a multi-cat home, several high spots in different rooms keep one cat from controlling them all. Older or arthritic cats may need a step or ramp to keep using a favorite perch.

Puzzle feeders and foraging

Food puzzles turn part of a meal into work. Options include hiding food in several places, scattering kibble or tossing pieces for the cat to chase, and using puzzle feeders to spread food across small, frequent meals. A veterinary review of food puzzles for cats, published in 2016, describes the main types, how to introduce them and how to troubleshoot, along with case examples in which cats showed health and behavioral improvements. The usual approach is to start with a very easy puzzle and make it harder gradually. A cat that gets frustrated and walks away needs a simpler puzzle, and a puzzle should never leave a cat short of its daily food.

A simple starting point is a muffin tin with a little kibble in each cup, or an egg carton or cardboard tubes with food tucked inside. Wet food can go into a flat lick mat or several small dishes hidden around the house. For cats on a weight-loss plan, any food used in puzzles comes out of the day's measured amount.

Signs a cat may need more stimulation

Cats rarely show boredom or stress in obvious ways. The following can be signs, but every one of them also has medical causes, and those come first.

• Overgrooming and bald patches. This is often put down to stress, but in a study of 21 cats referred with presumed psychogenic alopecia, 16 turned out to have a medical cause of itching, most often a food reaction, and only 2 had a purely behavioral problem.
• Peeing or pooping outside the litter tray. Urinary disease, constipation and arthritis all need ruling out before a stress explanation.
• Pouncing on ankles or swatting at other pets, especially in young cats with no other outlet for play.
• Constant demands for food or eating very fast.
• Night-time yowling or restlessness. In older cats, thyroid disease, high blood pressure and age-related cognitive change are possible causes.
• A marked change in sleep or activity. A cat that suddenly sleeps much more than usual should see a vet before boredom is considered.

Differences between breeds

Energy levels vary between individual cats, but breed descriptions give a rough guide. The Cat Fanciers' Association describes the Abyssinian as extremely active and playful, fond of high places, and quite capable of inventing its own games if it lacks toys. It notes that Abyssinians dislike being left alone for long. The CFA describes Bengals as keeping a kitten-like energy well into their senior years. Cats like these usually need several play sessions a day, plenty of climbing space and food puzzles, and some do better with a compatible companion cat.

At the other end, the CFA describes Persians as placid and mellow cats that can be persuaded to chase a toy but prefer attention and keeping their feet on the ground. Quieter cats still benefit from daily play, adjusted to shorter, gentler sessions and low perches, and portion sizes should match their lower activity.
