Plague in Animals

Plague is an infectious bacterial disease that is transmitted primarily by fleas on rats and other rodents. It can transmit through a flea bite or by direct contact with an infected animal, included rodents, wildlife, and pets. Household cats and dogs are known for developing plague much like humans. They are susceptible to get plague when they are allowed to roam and hunt in contaminated area. The incubation period is about 1 to 4 days. The areas that are most common for plague cases to appear are New Mexico (east mountains), California, Colorado, and Arizona.
