Dog-cat introductions are usually safer when they progress in stages rather than through immediate face-to-face contact.
Start with separate areas
Give each animal its own food, water, resting area and safe space.
Exchange scent first
Swap bedding or allow each pet to investigate areas the other has used.
Use controlled visual contact
Keep enough distance that both animals can remain calm.
Supervise early meetings
Use appropriate restraint and allow the cat escape routes and elevated spaces.
Slow down if needed
Persistent fear, chasing or aggression warrants professional behaviour guidance.
