Cats are more commonly bitten by snakes on their paws as they tend to swat. Dogs, on the other hand, investigate with their nose and mouth. It is not always possible to see the site of the snake bite, the puncture marks may be faint without any bruising, redness or swelling. There may not be a pain response either.
Snake bite symptoms in cats can vary greatly and tend to be inconsistent and transient. Felines can take up to 15 hours before showing signs! In dogs, the onset of signs is much quicker, generally within 1-6 hours. Early signs in cats include weakness, incoordination, off-balance and unsteadiness on the feet which appears almost like a drunk-like gait. This can progress to extreme lethargy and floppiness, unable to walk or even lift their head.
The reaction your pet will have to a snake may be determined by the type of snake, the amount of venom injected and where the snake has bitten. At the start of summer, when snakes become much more active, their glands are also fuller which leads to a more serious bite.
