Not a problem.  Cats have only a very limited window for transmission
of toxoplasmosis, and it has to be in the intestine.  Even then, cats
generally only shed for several weeks to a month, and develop immunity
against reinfection.
 
While ferrets are susceptible, like all warm-blooded animal, reports of
infection are extremely rare, and those cases did not result in disease.
