Adult fleas are blood sucking parasites and can only live on warm blooded animals (e.g. mammals, birds), should a flea fall off its host (e.g. in bedding, on floor, on ground) unless it is able to get back on a host it will slowly starve as it can no longer feed on blood.
Different species of flea are adapted to live on different species of hosts and if they are on a different species of host while they may be able to successfully feed they will be at a disadvantage (e.g. not being able to hold on to the host, not being able to digest the blood as well, not finding mates) compared to any fleas of the species adapted to that host.
