Signs of Snake Bite in Cats

The cat has been known for many years to have a higher resistance to tiger snake venom than any of the larger laboratory or domestic animals. It is also more resistant to brown snake venom. However, when the actual potency and venom output is considered, the higher resistance of cats is soon overwhelmed.

Generally the clinical signs of envenomation are varied and inconsistent. The commonest presenting signs in cats, which are more frequently delayed compared with dogs, are generalised muscle weakness and ataxia. Other signs such as mydriasis, vomiting and the absence of pupillary reflex are inconsistent, transient and could easily be overlooked by most owners. Cases which present with a complete flaccid paralysis and sub-normal temperatures have a poorer prognosis.

Additional information about systemic signs and symptoms can be found on the Snake Bite Signs page.
