Unlike companion cats raised at home, feral cats are more likely to be infected with parasites. Feral cats can transmit parasites not only to other cats but also to pets and people. This study was conducted to investigate prevalence intestinal parasites prevalence through the fecal examination of feral cats in Gunsan City. After making a suspension in Sheather's Sucrose solution, the feces were mixed and centrifuged, and then examined under a microscope. The results were revealed mostly unsporulated oocysts and sporulated oocysts of coccidia, followed by pinworm's eggs, which showed a relatively high infection rate. Scabies and mites were also found in the feces. Due to the behavioral characteristics of cats, they tend to remove the foreign objects from their fur through grooming, which is why a lot of hairs were observed in the feces, and it is thought that this is why scabies and mites were also found in the fecal examination results. The results of this study confirm that feral cats are exposed to those parasites. It is also thought that consideration should be given to expanding the TNVR (trap-neuter-vaccinate-release) program, which can reduce the number of feral cats.
