remind me: how long does "vet smell" last?

When one cat in a household spends time at the vet it's not unusual for the other cat(s) to react badly when that cat comes home. I assume the cat picks up foreign smells ("you've been with other animals, aiieeee!") or something. Erik, Baldur, and Embla grew out of this (presumably as the frequency of such visits increased), but I vaguely recall that the snarling and hissing would last a few hours.

Giovanni is still distressed this morning over Orlando's trip to the vet yesterday. How long does this last for other people's cats?

Thanks! It took until Saturday afternoon, but the hostilities have died down.
