In carnivores such as dingoes, foxes, cats, as well as native carnivores, the central nervous system is involved. They become very agitated, tremble, convulse and vomit. At other times the front feet are clasped together, clenched or used to scratch frantically at the cage walls. This tonic phase is then followed by a clonic phase in which the animals lie and kick or 'paddle' with the front legs and sometimes squeal, crawl around and bite at objects. During this phase the tongue and penis may be extruded, they eyes rolled back so that only the whites show and the teeth ground together.
Breathing is rapid but laboured, with some animals partly choking on their saliva.
Apart from baits, carnivores can also be poisoned by eating prey containing 1080, for example, poisoned rabbits or wallabies. In the process of fumigation, poisonous gas is released into rabbit warrens. The report concludes that tear gas is not humane, but did not have enough evidence to make a decision about phosphine. Pellets of aluminium phosphide are placed into warren entrances. They give off the poisonous gas phosphine when they get wet.
