Key takeaways

  • Think about each pet's personality first: a dog with a strong urge to chase, or a very nervous cat, may not suit a mixed home.
  • Give each pet its own safe space, with the cat's food, water and litter out of the dog's reach.
  • Swap scents for a few days before any meeting, then introduce on a leash through a gate.
  • Go at the slower pet's pace, and don't leave them alone together until they're reliably calm.

Before you start

Introductions go best when one or both pets have lived with the other species before. Watch how your dog reacts to cats on walks: a dog who ignores them is a good sign, while a dog who lunges or fixates may not be safe with a cat. A cat who is very nervous or already stressed may be happier as the only pet. Rescues can sometimes tell you whether a pet has lived with, or been tested with, the other species.

Set up the home

  • A cat-only room or area, closed off with a door or baby gate
  • Plenty of high places for the cat: cat trees, shelves, the tops of furniture
  • The cat's food, water and litter box out of the dog's reach
  • A separate bed and quiet place for the dog

The introduction, step by step

  1. Swap scents for a few days: rub a cloth on each pet and leave it near the other's bed, or swap blankets.
  2. Feed them on opposite sides of a closed door, moving the bowls closer as they stay relaxed.
  3. Let them see each other through a baby gate for short sessions, with the dog on a leash. Reward the dog for calm behavior and for looking away from the cat.
  4. When both are relaxed, allow the cat into the same room with the dog still on a leash. Let the cat choose whether to approach.
  5. Gradually lengthen supervised time together. Keep them separated when you're not home until you're confident.

Signs to slow down

  • The dog stares, stiffens, whines or lunges
  • The cat hisses, growls, flattens its ears or stops eating or using the litter box
  • Either pet seems unable to settle

Go back a step and give more time. If progress stalls, ask your vet or a qualified behaviorist for help.

Questions, answered

How long does it take for a dog and cat to get along?

Some pets settle in days, others take weeks or months. Let the more nervous animal set the pace.

Which dog breeds are good with cats?

Individual personality matters more than breed, but dogs with a strong chase or prey drive need extra caution. Ask a rescue about a dog's history with cats.

Should a cat and dog share a water bowl?

It's best to keep the cat's food and water separate and out of the dog's reach, so the cat can eat in peace.
