How to Introduce a Cat to a Dog

Cats and dogs can share a home well. The secret is slowness: scent first, sight second, meetings last.

Prepare separate spaces

Give the cat its own room with food, water, a litter box, hiding spots, and a scratcher. Keep the dog out of that room entirely at first. The cat needs a safe base before it meets anyone new.

Swap scents first

Exchange blankets or bedding between the two animals so each learns the other’s smell. Feed them on opposite sides of the closed door, so good things happen near the stranger’s scent. If either refuses to eat, move the bowls further from the door and try again.

First sight, with a barrier

Let them see each other through a baby gate or a cracked door, for a few minutes only. Reward calm behavior on both sides with treats. Hissing or growling is communication, not failure: end the session calmly and try again later.

First meetings, short and supervised

Keep the dog on a leash and let the cat move freely. Keep meetings short and end before anyone gets stressed. The cat must always have an escape route and a high place to retreat to. Never hold the cat in front of the dog — a held cat cannot flee, and fear turns into a fight.

If the new arrival is a kitten

Kittens need their own settling-in time before any introduction. Set up Kitten’s First Week at Home first, and only start introductions once the kitten is eating, playing, and using the litter box confidently.

If it goes wrong

Go back one step. More distance, shorter sessions, slower progress. If chasing persists or either animal is terrified, keep them separated and slow down further. Patience over days or weeks beats one forced meeting that ruins trust.

When to get help

If either animal stops eating, hides for days, or shows sudden behavior changes, see a veterinarian promptly. Stress can hide health problems, and a vet visit rules that out.
