Cat and dog fleas are very similar in appearance and both species can live on both cats and dogs. Humans are mainly attacked by cat fleas. A cat or dog may have a light infestation of fleas without the human inhabitants knowing it, but if the pets are carrying large numbers of fleas, then there is naturally a greater likelihood of humans being bitten. A heavy infestation may occur if the cat or dog is removed from the house, for then the insect has no alternative but to feed off us. In such cases one may comfort oneself with the fact that the cat and dog fleas cannot breed without their principle hosts, and so eventually the infestation will die out on its own. On the other hand, they can live for months on a diet of human blood, so it needs an unusual amount of patience to wait until the fleas die of old age.
