Do river otters have any diseases that affect them when they are over populated?

Yes, river otters can be affected by diseases when their populations become overcrowded. Overpopulation can lead to increased stress, which may heighten their susceptibility to diseases such as distemper, parvovirus, and infections caused by parasites. Additionally, overcrowded environments can exacerbate the spread of these diseases, leading to higher mortality rates and impacting the overall health of the population. Proper habitat management is essential to maintain balanced otter populations and reduce disease outbreaks.
