A single rabid cat from an unmanaged feral colony near a hotel in Cecil County, Maryland scratched and bit two people on August 8, 2024. Within days, public health officials were scrambling to track down 309 hotel guests across 27 states and Canada who may have been exposed.
The CDC published its full report in the Morbidity and Mortality Weekly Report in August 2025. The findings are a case study in how one unmanaged cat colony can trigger a multi-state public health emergency.
What Happened
The colony of roughly 20 feral cats had established itself near a hotel in Cecil County. Nobody managed them. Nobody vaccinated them. They just existed, breeding and roaming the property.
On August 8, one of the cats turned aggressive and attacked two residents, biting and scratching them. The cat was captured and euthanized. It tested positive for rabies on August 10.
Rabies is nearly 100 percent fatal once symptoms appear. There is no cure. The only option is post-exposure prophylaxis (PEP), a series of shots that must be administered before symptoms develop. The clock was ticking for anyone who had contact with that colony.
The Response
Health authorities had to identify every guest who stayed at or visited the hotel during the exposure window. That meant tracking 309 people scattered across 27 U.S. states and parts of Canada. The response pulled in 29 separate jurisdictions and consumed over 450 hours of personnel time.
Of the 197 people who completed risk assessments, three were confirmed exposed and received PEP. No human rabies cases occurred - but only because the response was fast enough.
The CDC's report included a pointed warning: "TNR programs that do not incorporate rabies prevention components might inadvertently increase risks."

The Bigger Picture
Cats are the most frequently reported rabid domestic animal in the United States. Between 200 and 300 cats test positive for rabies annually. The CDC estimates that rabies PEP costs linked to cat exposures run roughly $33 million per year.
Feral colonies are the epicenter of this risk. Unvaccinated, unmonitored, and often fed by well-meaning residents who have no idea what diseases are circulating in the group. A fed colony is not a managed colony. Feeding keeps them alive and concentrated. It does nothing about rabies, feline leukemia, or the dozen other pathogens these animals carry.
Cecil County got lucky. The cat attacked people near a hotel with a guest registry, making contact tracing possible. Imagine the same scenario at a park, a strip mall parking lot, or a school playground. No registry. No way to trace who walked past and got scratched.
The Cost of Doing Nothing
Every unmanaged feral colony is a ticking clock. Not a question of if, but when. The Cecil County incident required 29 jurisdictions, 450 hours of work, and PEP treatment for confirmed exposures - all because nobody bothered to manage 20 cats.
The math is simple. Vaccinate, sterilize, and manage the colony - or accept that one day a rabid cat will turn a hotel into a multi-state health emergency. Maryland found out. The question is who is next.
