my boa has fleas in his tank and im wondering if i need to treat him with something the fleas came from my cats lying on top of his tank , please help and do fleas actually bite a snake
usually fleas dont attack snakes. snakes can have fleas ON them but they can't 'have fleas' the way cats do. no fur = no fleas, but remember that snakes can have mites and ticks -- these do bite.

if you're sure it's fleas but not mites or ticks, just clean the tank well to get rid of those that got into the tank already and do not let your cat close to the tank if you dont want more fleas there
ya they do
