There have been growing concerns about the poison a cat excretes through the upper incisors located along the top jaw. In the wild, a domestic cat will inject this venom in to their target prey to separate and organise the inside organs into groups. This can take several minutes to take full effect. An impatient cat will tap or roll the prey to speed up the process. Although potent, the venom is ineffective on larger mammals so there is no immediate danger to the general public.
