Each year in the U.S., several thousand cases of rabies are diagnosed in wildlife, particularly among reservoir species (eg, raccoons, skunks, foxes, bats), and several hundred cases are diagnosed in domestic animals. Cats account for nearly 50% of domestic animal cases.¹ In countries where canine rabies has been controlled but wildlife rabies remains, cats are often a greater source of rabies exposure to humans than are dogs² and are considered highly susceptible to infection and highly capable of transmission.^3,4 There is some debate as to whether cats are more susceptible to rabies than dogs, and results appear to be dependent on the challenge virus used in experimental studies.² Cats also appear more susceptible to wildlife isolates but less susceptible to canine isolates.² Specific feline rabies strains have not been documented, and intraspecific transmission among cats appears limited.³

• The site of rabies inoculation affects incubation time; the farther from the brain, the longer the incubation time.
• In dogs, the average incubation period is 3–8 weeks (range, several days to >6 months).³
• In cats, the average incubation period is 4–6 weeks.⁵
• Dogs and cats as young as 8 weeks of age have been documented with rabies,^6,7 and it is likely that younger animals can be at risk.

• Clinical signs of rabies can be highly variable, but behavior changes are usually seen first.
• Patients shed virus in the saliva a few days before clinical signs develop.
• Once signs develop, progression to death is rapid. 
• Prodromal stage (1–3 days’ duration):
• Dogs: Lick site of inoculation; seek solitude; are more anxious/docile/apprehensive/irritable; develop fever, lethargy, snapping
• Cats: Similar to dogs, but behavior may be more erratic
• Furious stage, or the classic “mad dog” stage (1–7 days’ duration):
• Dogs: May experience restlessness, irritability, enhanced response to auditory and visual stimuli, changes in bark, choking sounds, drooling, ataxia, seizures, coma; are excitable and aggressive; behavior includes snarling, biting, barking, or snapping at imaginary objects; attempt to eat inanimate objects
• May lead to death
• Signs are similar for (and more common in) cats, who may become exceedingly vicious and strike out suddenly
• Paralytic stage (1–10 days’ duration):
• Typically follows furious stage
• More common in dogs than in cats
• Signs include paralysis (causing jaw to stay open), apparent difficulty swallowing, saliva dripping from mouth, ataxia, paralysis, coma, respiratory failure
• May lead to death

• Immediately wash wounds with soap and water for 15 minutes.
• Apply first aid to bite wounds.
• For a canine or feline patient bitten by a rabid animal or a rabies reservoir species:
• If unvaccinated, the patient should be euthanized.
• If the owner declines, the patient should be placed in 6-month quarantine and vaccinated against rabies at the start of the quarantine or one month before release. 
• An up-to-date, vaccinated patient should be revaccinated immediately and placed in 45-day quarantine.
• Patients previously vaccinated but past-due for boosters should be considered on a case-by-case basis while keeping in mind the local or state laws regarding such cases. In some states, an animal even one day past-due for a rabies booster would be considered unvaccinated. 
• Other considerations include: severity of exposure, time elapsed since last rabies vaccination, number of rabies vaccinations during the patient’s life, current health status, and local rabies epidemiology.¹³
• For a human bitten by a pet:
• Any dog, cat, or ferret that bites a human, regardless of the pet’s vaccination status, requires 10-day quarantine.
• An animal shedding rabies virus at the time of the bite will demonstrate signs of rabies within 10 days.
• If the animal demonstrates signs of rabies during the 10 days, the animal should be euthanized and the head submitted for testing.
• The location of the quarantine depends on local laws and circumstances. Consult the state health department and local animal control agency.

• All veterinary practice team members working with animals should be vaccinated against rabies.
• Pre-exposure vaccination protects against unnoticed exposures and is much less costly than post-exposure prophylaxis for unvaccinated persons.
