It's the circle of life - fleas evolved, and they must have something to feed on! Part of the food chain - they help tapeworm's lifecycle too.
Human fleas used to be very common, and still are in some parts of the world until we learned to control them. Now we're learning to control animal fleas.

Because they need a ride..lol. !! Actually, if a pet is an outdoor pet, depending on the season, fleas are a part of nature just like mosquitoes. I have 2 cats and one dog . Animals can catch fleas from another pet that has fleas. My dog has been immunized for Lyme Disease. Every month, along with his heartworm medications, I use Frontline Plus every month. My cats are outdoor pets but, only during the warmer months. I use a powder on them to protect them, Hartz 2 in 1. I use this faithfully. I haven't had any problems with fleas, thankfully . A flea infestation is quite a problem.

flea is the common name for any of the small wingless insects of the order Siphonaptera (some authorities use the name Aphaniptera because it is older, but names above family rank need not follow the ICZN rules of priority, so most taxonomists use the more familiar name). Fleas are external parasites, living by hematophagy off the blood of mammals and birds. Genetic and morphological evidence indicates that they are descendants of the Scorpionfly family Boreidae, which are also flightless; accordingly it is possible that they will eventually be reclassified as a suborder within the Mecoptera. In the past, however, it was most commonly supposed that fleas had evolved from the flies (Diptera), based on similarities of the larvae. In any case, all these groups seem to represent a clade of closely related insect lineages, for which the names Mecopteroidea and Antliophora have been proposed.
Some well known flea species include:
* Cat flea (Ctenocephalides felis),
* Dog flea (Ctenocephalides canis),
* Human flea (Pulex irritans),
* Northern rat flea (Nosopsyllus fasciatus),
* Oriental rat flea (Xenopsylla cheopis).

No, they aren't "made" to have them. Fleas are parasites and will feed on any animal they can find. It's up to you to protect them from fleas by keeping them on a trustful medication such as Advantage, Revolution or Frontline.

any mammal can have fleas. they suck blood out of anything. cats and dogs just tend to get dirty and their hair is the perfect environment.

It's not like they're born with them. Fleas come from unclean places, most commonly, dead insects, feces, rotten vegetation, etc
