Most people bring the second cat home, let the two of them meet to “see how it goes,” and spend the next six months trying to undo that afternoon.

This is the other way. Six stages, in order, each with a gate: exactly which signals mean advance, and which mean drop back one stage today. No guessing whether it’s been long enough.

What’s inside
· Six stage spreads — what to do daily, and the green and red lights that decide when you move on
· The printable gate map: the whole method on one page
· The arousal ladder — read ears, eyes, tail and posture before a session goes wrong
· Troubleshooting by symptom, including what to do after a real fight
· Five printables: 30-day log, stage tracker, session card, vet prep sheet
· 19 named sources — every organisation credited on the page it appears on

Who it’s for
Anyone bringing home a second cat, and anyone whose introduction has already stalled or blown up.

What it isn’t
Not veterinary advice. If a cat has stopped eating or isn’t using the litter box, that’s a vet appointment, and the guide says so on page 2.
