What causes drooling in cats?

Some cats drool naturally but others may have done something to start drooling for example they may get something stuck in their mouth or throat. The most common causes are if your cat licks frogs/toads or if it gets stung in the mouth by a wasp/bee. if your has never drooled before and does it for more than a few hours you should take it to the vet in case there is something stuck in its mouth.
