Has anyone consideredConsider that Cats like to lick their paws?. If their claws were toxic wouldn't they just killwould poison themselves??. I don't think it's possible.
On the otherhand, I must argue thatother hand eating venomous animals/objects does not necessarily make itsan animal's claws toxic. Consider koalas. I don't think their claws are toxic even though they eat eucalyptus.
