The botfly proliferates by laying eggs on blades of grass or in nests, where they hatch, releasing maggots that crawl onto the skin of passing animals. Cuterebra is a bee-like fly which lays her eggs in places where target mammals will come in contact with them. The mature fly lays eggs near the nest of rabbits or rodents. Cats are accidental hosts of Cuterebra larvae. Larvae causing neurologic or respiratory signs represent more of a diagnostic challenge. Most cysts containing bots are found around the face or neck, Rarely, larvae may enter the anterior chamber or globe of the eye causing chemosis, blepharospasm, serous ocular discharge, and exudative uveitis with blindness, Typically, there are no signs of disease or distress in cats or dogs due to larvae localized subcutaneously, Neurologic disease, which is reported more often in cats than dogs, occurs when larvae migrate through the brain.

Flush the hole with a dilute betadine solution, and apply a topical antibiotic ointment, like neosporin. The eggs hatch, and the larvae either penetrate the skin, are ingested when the animal grooms, or they enter the animal's body through a natural opening, … This ulcerative lesion with a purulent exudate is typical of this infection. Normal hosts are rabbits, squirrels, chipmunks, and mice. In warmer climates, adult flies can emerge from soil and lay eggs throughout the year.

Hatched larvae crawl into the fur of a mammalian host, enter the host through a natural body opening, and migrate to a subcutaneous site. They don't usually become infected, and will heal quickly. Females lay eggs in groups of 5-15 on grass stems, wood chips, and bark along narrow trails or rodent runs near the opening to the rodent burrow; some species actually enter rodent burrows to lay their eggs. FBs consisting of vegetative material are apt to also carry bacteria or fungal organisms into the anterior chamber and should be carefully removed.

In any ferret with cutaneous myiasis, remove the larvae intact, if possible, to avoid leaving a nidus of infection or precipitating a systemic response. Cuterebra in cats is just as serious as cuterebra in dogs. Clinical signs are usually not apparent in the normal rodent or lagomorph host. Furuncular myiasis: subcutaneous cysts with mature third-instar bots in the skin, Neurologic and other disease manifestations from the migration of young bots through deeper tissues of the body, Respiratory distress or upper respiratory disease from migration of young bots through the trachea and diaphragm.

If the lens is penetrated by the pellet, lens removal by phacoemulsification should be considered, as the gradual release of lens material through the lens wound causes a progressive and eventually medically refractory anterior uveitis. Michelle was horrified at the thought of having some nasty creepy crawly parasite in her dear little Foxy.
