Yeah, absolutely. A bit rowdier but nothing more. She wasn't even collared or chipped (Aside from strangling them with it, they always find a way to remove the collars) so it was a really happy shock she came back. Another did it for a few weeks too. Cats live off very familiar territory and don't stray as far as people think. If he's lost his way a bit, it'll take a while to regain his compass, but unless you've moved into a new place, they always find their way back.
When I was a kid, the one cat I had disappeared for a whole frikking year and still managed to come back, and this was in a country where cats were basically treated as pigeons.
In cats I trust. They're hardy bastards. Stay optimistic.
Had you gotten a replacement cat by then already?
