Solenodons, short-tailed shrews, the Eurasian Water Shrew, and the European Mole inject venom into prey by biting it; the venom is transferred through teeth. Male platypuses inject venom through spurs on their back legs; female platypuses and both sexes of echidnas also have these spurs, but they cannot inject venom.
there saliva has venom in it
No. A Ring-Tail Possum does not have venom.
Water shrews have a venomous saliva, but they are not able to inject it into a human's bloodstream, as a viper may. Thus, a bite is completely harmless (other than a little blood).
They have venom glands in the back of their mouths that produce a toxin that other organisms react to. Only venomous snakes can produce venom.
Cuban Solenodon (Atopogale cubana) & Haitian Solenodon (Solenodon paradoxus) Solenodons look similar to very large shrews. They both have venomous bites; the venom is delivered from modified salivary glands via grooves in their second lower incisors.Platypus (Ornithorhyncus anatinus) Males have a venomous spur on their hind legs. Echidnas, the other monotremes, have spurs but no functional venom glands. Eurasian water shrew (Neomys fodiens) Capable of delivering a venomous bite. Northern Short-tailed Shrew (Blarina brevicauda) Capable of delivering a venomous bite. Southern Short-tailed Shrew (Blarina carolinensis) & Elliot's Short-tailed Shrew (Blarina hylophaga) Possibly have a venomous bite.*** I did not edit the above statement because it is true, however "Venomous" and "Poisonous" are two completely different things. Venom is a harmful toxin injected via a bite or sting. Where as Poison is secreted through a gland or glands and is harmful to the touch or by ingestion. The two words are not interchangeable. I do not know of four "Poisonous" mammals, but I do know of one, The Slow Loris (Nycticebus Javanicus). ***
No
No they do not produce venom.
anacondas do not produce venom they squeeze their prey to death
A snake may, at times, inject all the venom in its venom sacs. It will take a number of weeks to produce more venom to replenish the supply. During this time the snake has no protection and is unable to obtain food. Rattlesnakes may inject all their venom if they are highly agitated or frightened.
well, the glands in the snake produce the venom, which goes to its saliva, then, it spits it out to its prey OR predators.
No. Cats do not produce venom.
