Almost all furry pets get ticks and fleas. Dogs, cats, rabbits and hamsters are prone to fleas and ticks.
They feast on insects if given the chance, and rarely carry ticks; they groom often and eat their ticks. The average opossum eats 1-3,000 ticks a year. They may have fleas, but the fleas are small and not numerous.
Some examples of animals that live on the surface of other animals include certain species of mites, ticks, and parasitic insects. These organisms are known as ectoparasites because they live on the outside of their host's body, feeding off their blood or tissues. Examples include fleas, lice, and certain types of gnats.

Microorganisms that live on fleas, lice, ticks, and mites are called ectoparasites. These organisms often include various types of bacteria, protozoa, and viruses that can either inhabit the surface of these parasites or live within them. They can play roles in the transmission of diseases to their hosts or other organisms. Some common examples include Rickettsia and Bartonella species, which are associated with ticks and fleas.
