TL;DR
- Cats are not little dogs. They are solitary, territorial animals that have kept most of their wild nature.
- Their language is subtle, and most owners never learn it.
- We keep them in small homes, often with other cats they didn’t choose. It is our job to meet their natural needs, not theirs to adapt.
- Chronic stress is linked to behaviour problems and to illness, including painful bladder disease.
- Most cats need five things: safe places, separated resources, play, predictable human contact and respect for their sense of smell.
- With more than one cat, the rule is one of everything per cat, plus one extra, in different places.
- A male cat straining to urinate is an emergency.
- Every home is different. I can assess yours in person, with your cat in it.
Your cat isn’t being difficult
A cat that stares at another cat, hides all day, scratches the couch or toilets outside the tray is rarely being spiteful. It is communicating, in a language most of us never learned.
Stress-related issues are the most frequent reason I am called to see cats at home. Most of those cats have nothing wrong with their character. They are living in a home that doesn’t suit the animal they are.
Cats are not little dogs
Dogs were shaped over a very long time to live alongside people and work with them. Most of them took to it remarkably well.
Cats didn’t. The relationship started about 10,000 years ago, when cats moved in to hunt the rodents around grain stores. It needed no change to the cat’s instincts (Ellis et al. 2013). Today’s pet cat still behaves much like its wild ancestor, the African wildcat (Ellis et al. 2013).
Here is the comparison I use. Release a pet dog and a pet cat into the bush and I know which one I’d bet on. The cat already knows how to hunt, hide and avoid trouble. Most dogs would be waiting for someone to feed them.
The language most people never learn
Cats communicate through posture, facial expression, scent and avoidance. None of it is loud. A cat in distress is more likely to hide, stare, block a doorway or wait until the house is quiet than to cry out.
Cats also protect themselves by not showing pain or illness, which is why they are so often mistaken for independent animals that don’t need much care (Ellis et al. 2013). Owners usually only notice once the behaviour becomes a problem and gets labelled as bad, inappropriate or aggressive (Ellis et al. 2013).
Scent matters as much as sight. Facial rubbing and scratching mark a space as safe and familiar (Ellis et al. 2013). When we clean those marks away, or move things around, a cat reads it as a change to its territory.
The root of the problem
I’ll be blunt. Most of the problems I see start with us.
Cats evolved as solitary hunters that hold territory and avoid conflict. We take them, shrink that territory to a few rooms, and often add other cats they didn’t choose. Then we are surprised when they get stressed.
The cat isn’t failing to adapt. We are failing to provide. Cats have natural requirements, and meeting them is our responsibility. It is the price of keeping a wild-natured animal indoors.
Why this matters for health
Stress and disease are linked. Even calm-looking cats can have raised stress hormones (Ellis et al. 2013). Around 55 to 65 percent of feline lower urinary tract disease cases are feline idiopathic cystitis, a bladder inflammation with no infection or stone behind it. Cats with this condition respond to changes in their environment, and managing stress is a core part of treatment (Buffington et al. 2006; International Cat Care 2025a).
Signs your cat may be stressed
Acute stress is obvious: crouching, flattened ears, hissing, trying to escape. Chronic stress is quieter. Watch for:
- Hiding more, resting more, playing less
- Changes in eating, grooming or toileting
- Spraying or toileting indoors
- Overgrooming
- Becoming withdrawn or reactive
- Jumping at small noises
(International Cat Care 2025c)
Any of these can also be medical, so a vet check comes first.
What every cat needs
The AAFP and ISFM environmental needs guidelines set out five pillars (Ellis et al. 2013).
- A safe place. A hiding spot, ideally raised, that your cat can retreat to. Leave it alone when it is in use.
- Separated resources. Food, water, litter, beds and scratching posts in different locations, with at least two of each.
- Play and hunting. Ten to 15 minutes of wand-toy play a day, ending with a catch and a small meal. Puzzle feeders help.
- Predictable, cat-led contact. Let your cat start and end every interaction. Pat the head and cheeks, not the belly.
- Respect for scent. Don’t wipe away facial rub marks, avoid strong cleaners and scented litter, and wash bedding on rotation.
Protecting the bladder
Three changes make the biggest difference for urinary health (International Cat Care 2025a):
- Wet food, or water added to meals, to dilute the urine.
- Water in several rooms, in wide ceramic or glass bowls, away from food and litter.
- Large, unscented, uncovered litter trays, scooped at least once a day.
Never punish a toileting accident. A cat that suddenly stops using the tray may be in pain.
More than one cat changes the maths
Cats can live in groups when resources are plentiful, but they choose their own friends, and those are usually relatives (Ellis et al. 2013). In most homes, we choose the housemates. Some cats end up sharing a house without ever bonding, which leads to more tension (Rodan et al. 2024).
Tension affects somewhere between 62 and 88 percent of multi-cat homes (Rodan et al. 2024). Staring is the most commonly reported sign, followed by chasing, stalking and fleeing (Rodan et al. 2024). Cats rarely fight openly. They avoid, block and wait.
What helps:
- One per cat, plus one extra of every resource, in different locations (International Cat Care 2025b).
- Separate feeding, out of sight of each other, even for bonded cats.
- Litter trays spread through the house. Not side by side, and not in hallways, near cat flaps or next to noisy appliances.
- Hiding places with two exits, and perches at different heights.
- Individual play with each cat at least twice a day (Rodan et al. 2024).
Don’t punish cats for tension, and don’t put your hands into a stand-off. Place a cushion or piece of cardboard between them and redirect each cat to a toy (Rodan et al. 2024).
Adding a new cat
In a large survey of multi-cat homes, 73.3 percent of owners said tension began when a new cat arrived (Elzerman et al. 2020, cited in Rodan et al. 2024). A slow introduction through a separate room, scent swapping and short supervised meetings takes weeks to months. If tension appears, go back a step (Rodan et al. 2024).
When to see a vet
Emergency, go now: a male cat straining to urinate with little or no urine, or a cat in increasing distress, vomiting or lethargic with a painful belly. A urethral blockage can be fatal within 24 to 48 hours.
Within 24 hours: blood in urine, toileting or spraying indoors, a cat that has stopped eating or hides all day, wounds after a fight, or any marked change in behaviour.
Why a home visit shows what a clinic can’t
In a clinic, I see your cat in the one place it is least likely to behave normally. Cats forced out of familiar territory respond by hiding and avoiding (Ellis et al. 2013), and I can’t see the litter tray that gets ambushed in the hallway or the perch that one cat guards.
At home, I can see all of it. I look at where resources sit, how your cats move through the house and which cat uses which spaces, then work out changes that suit your home, your cats and your routine. There are no time limits and no waiting room, and your cat stays in its own territory.
I work alongside your regular clinic, not instead of it.
Book a home visit
If your cat is showing any of these signs, or you want to start a new or second cat off well, book online or get in touch through the Personalised Mobile Vet website. I cover Greater Brisbane, Ipswich, Logan, Moreton Bay, Redland City and the Lockyer Valley.
They speak. You just have to listen.
