At her rental house, which she named "The Critter Café," Christine Bishop was a well-intentioned rescuer of stray cats, dogs, and lost ducks. Then someone dropped off a cage of pet rats. Soon neighbors were complaining of a stench from the house, and could see rats running outdoors.

When officials entered the house, they found the rats had totally over-run the house. They initially removed 1,500, and estimated that at least a 1,000 remained. The property-owner, Dale Carr, says the rats are feral, so "they'll bite, carry ticks and fleas, and are susceptible to rabies and disease." Township Supervisor Brian Werschem says this number of rats "… can breed 1,500 rats every three weeks, so if they're not removing them at a rate of 100 per week, they're not making progress."

The next step in the plan is to wrap the house and fumigate it, which "could cost the owner nearly $30,000, not including cleanup and disposal cost."
