I don't wanna derail this by getting too off-topic, but IMO transmissible cancers are just too fascinating not to ask -- where has this been documented in humans? As far as I knew the Tasmanian devil facial tumors were the first and only transmissible cancers ever recorded -- I'd be really interested to know if it's been seen in humans as well!
