After 24hrs or as long as you like after 24hrs. The longer the better.

OK I can leave it a few days and no cat's paw prints either.

No cat? You did check where it was before you poured?

About 15 years ago I had a Koi pond built, about 6 feet deep. The day after
the base was poured there were some very, very deep paw prints. but no
missing cat, well not mine anyway.
