How to introduce a cat to a dog — the 14-day AU plan

Rushed cat-dog introductions cause permanent stress for the cat and at least one bite for the dog. Here's the slow plan that actually works in an Australian home.

Cats and dogs can live together — but only with a slow introduction. Rush it and the cat develops a stress response that lasts months, or the dog gets a face-claw injury. Here's the 14-day plan used by AU behaviourists.

Before you start: is this dog suitable?

Some dog breeds and individual dogs do not co-exist with cats safely. High prey-drive working breeds (kelpies, cattle dogs, terriers, sighthounds) struggle most. Greyhounds adopted retired from racing require specific cat-testing before placement — most AU greyhound rescues do this formally.

If your dog has chased a cat outside, fixated on small wildlife, or shown a "high prey response" (rigid posture, intense staring, hard mouth on toys), get a behaviourist assessment before bringing a cat home. $200–350 for the consult; saves the cat's life.

The setup (before the cat arrives)

• Cat-only sanctuary room. Spare room, laundry, walk-in robe with door. Litter, food, water, scratcher, bed. Will be the cat's exclusive zone for at least 5–7 days.
• Two baby gates — for visual-but-no-contact phase.
• Feliway Friends + Adaptil diffusers — one of each in the shared living area, plugged in 2–3 days before the cat arrives.
• Cat-height vertical territory. Shelves, a cat tree, a window perch. Cats feel safe up high; this is non-negotiable in a dog household.

Days 1–3: Scent only

Cat lives in the sanctuary room with door closed. Dog never sees or smells cat directly. Daily routine:

1. Rub a soft towel on the cat's cheeks; place it under the dog's water bowl.
2. Rub another towel on the dog's neck; place it under the cat's bowl.
3. Both animals now associate the other's scent with mealtime.

Watch the dog at the towel. Curiosity is fine. Fixation (rigid, prolonged stare, lip-licking, freezing) is a warning sign — extend this phase another 2–3 days.

Days 4–7: Swap rooms

While the dog is out on a walk, let the cat explore the main house for 30 minutes. Then return the cat to the sanctuary, bring the dog in. The dog spends 5–10 minutes in the cat's room — supervised. They're each smelling the other's territory now.

Days 8–10: Visual, no contact

Use the baby gates — stacked or single — to create a visual barrier the cat can see over but the dog can't cross. Or prop the door 5–10cm with a wedge. They can see each other; they cannot reach through.

Do this at the dog's feeding time. The dog is occupied with food; the cat associates the dog's presence with the dog being not-interested. Sessions: 5–10 minutes, multiple times a day. End before either animal is stressed.

Days 11–14: Leashed introductions

Open the door, dog on a short leash, calm. The cat has full access to retreat to the sanctuary room. First session: 5–10 minutes. The dog should be in a calm sit or down — reward calm with treats every 30 seconds.

If the cat hisses and retreats: normal, expected, fine. The cat is communicating boundaries. Don't intervene unless the dog lunges.

Increase session length day by day. By day 14, most pairs tolerate each other in the same room for 30+ minutes. Trust takes 3–6 months to fully build.

When it isn't working

Warning signs after week 2 that warrant a behaviourist:

• Cat hiding 90%+ of the day, won't eat
• Dog cannot break stare or settle in cat's presence after 5+ minutes
• Any actual contact attempt (dog lunging or grabbing) — pause introductions immediately
• Cat showing redirected aggression (attacking household members)

AVSAB-certified or CABTSG-affiliated behaviourists. Don't try to push through serious warning signs without help — both animals' welfare is at stake.

The forever truth

A cat-and-dog household works when the cat has guaranteed vertical territory, separate food and water on a counter or shelf the dog can't reach, and a closed-door sanctuary for the cat to retreat to. Many AU households have these long-term, not just during introductions. Plan the layout permanently.
