Your puppy notices the cat beyond a gate, then looks back at you. That's a useful early win. They don't need to touch noses for the introduction to move forward.
Start with separate living areas, then introduce scent and sight gradually. Protect the cat's access to food, litter, and rest while rewarding the puppy for calm observation and looking away. Let both animals' behavior set the pace, and keep secure separation whenever you aren't actively supervising.
Give the cat a puppy-free home base
Before the puppy arrives, prepare a cat-only refuge with food, water, litter, comfortable resting places, and hiding options. Keep food, water, litter, and resting places apart within the room.
Provide stable elevated places the cat can reach, along with routes away from puppy access. Make sure the cat can reach and leave each perch without being cornered by the puppy.
Check doors and gates against the actual animals. Can the puppy squeeze through, climb, or jump? Can the cat leave without entering the puppy's reach? Use a closed door when a gate isn't reliable.
Blue Cross recommends a secure cat refuge and gradual introductions. A carrier is a transport tool, not a substitute for a room where the cat can move and meet daily needs.
Begin with separate routines and scent exchange
Give both animals time to eat, rest, play, and toilet comfortably in their separate areas. Use the first-week puppy routine to organize care without repeated surprise access to the cat.
Exchange familiar bedding or other safe items carrying each animal's scent, allowing voluntary investigation. Don't put an unfamiliar scent directly in the cat's sleeping spot if that makes them avoid it.
Offer familiar activities on opposite sides of a closed door at enough distance that neither animal feels compelled to approach. If either stops eating, fixates at the door, or cannot settle, increase distance or end the session.
There is no universal number of days to complete this stage. Look for normal daily behavior and easy recovery from noticing the other's presence.
Use a secure barrier for the first views
Arrange a short session across a secure see-through barrier, with an adult holding the puppy's leash slack. The puppy should already be comfortable with the leash. Keep the cat free to stay away or leave on their side.
Start far enough back that the puppy can notice the cat and still respond to you. Reward calm observation and turning away. You can use a familiar easy cue if it helps, but don't repeat cues while the puppy keeps staring at the cat.
If the puppy cannot disengage, increase distance or end visual access. If the cat hides, restore privacy rather than carrying them into view.
The shy-cat bonding guide can help you support comfortable daily life when the cat is avoiding people or shared spaces. Avoidance isn't a reason to speed up meetings.
Check both animals before allowing closer contact
Consider a brief supervised meeting in the same room only after both animals are repeatedly comfortable across the barrier. The puppy should be able to look away, and the cat should be able to observe or leave without being pursued.
Keep the puppy on an adult-held slack leash and preserve the cat's escape routes. Have a barrier ready to restore separation. Don't remove every safeguard because one meeting looked calm.
Progress can mean the cat continues resting on a perch while the puppy settles at a distance. Friendship and shared sleeping spots aren't necessary outcomes.
An exciting new location, a running cat, or a more energetic time of day may make the situation harder again. Return to barriers when needed instead of testing whether the puppy will chase.
Treat staring and chasing as reasons to act
A hiss or growl means create space; don't punish it. Persistent hard staring, darting lunges, inability to respond, or pursuit of the cat needs secure separation and qualified reward-based behavior assessment.
Never allow chasing on the assumption that it's harmless play or that the cat will teach the puppy a lesson. Don't hold the cat for a greeting or exhaust the puppy in hopes of forcing a successful meeting.
East Bay SPCA's introduction guidance includes compatibility and predatory-risk considerations. Some pairings cannot safely share space. A professional can help assess whether long-term managed separation is realistic or whether placement options need discussion with the rescue the people responsible for their care.
Keep monitoring life between meetings
Check that the cat still eats, drinks, rests, and uses the litter box normally. Injury, appetite or toileting changes, and ongoing distress need veterinary advice. The puppy's behavior matters outside formal practice, too: constant watching of the cat's door is information to share with a professional.
Maintain separation whenever active supervision isn't possible. A calm greeting doesn't establish safety for an empty house, and no introduction method can guarantee compatibility.
