Are barking frogs poisonous

My cat just brought a Rocket Frog into the house and he was foaming really badly from the mouth.My husband rushed the cat to the bathroom and washed the cats mouth out.He said that the poison was on the frogs back and is gelatinous and you have to rinse the poison out of and off of his mouth as quickly as possible.The cat seems to be ok ,although it's only been ten miniutes since it happened.
