Due to cats' natural hunting instinct, their ability to adapt to different environments, and the wide range of small animals they prey upon, both feral and free-ranging pet cats are responsible for predation on wildlife, and in some environments, considerable ecological harm. Cats are disease carriers and can spread diseases to animals in their ...

Cats are believed to have been a factor in the extinction of the only mainland bird species to be lost since European settlement, the paradise parrot. [18]
The venom of Vespa luctuosa has the highest recorded toxicity to mice of any wasp species tested. The LD 50 of the venom is 1.6 mg/kg. The toxicity (measured against mice) per weight of Vespa luctuosa venom is higher than that of the larger Asian giant hornet (Vespa mandarinia), which has an LD 50 of 4.0 mg/kg, but which is responsible for many more human deaths than Vespa luctuosa due to the ...
