2 Miss. Code. R. 101-2-12-109.01
Rabies Vaccination. All dogs, cats, and ferrets three (3) months or older transported or moved into the state for any purpose shall be accompanied by proof of current rabies vaccination per guidelines outlined in the National Association of State Public Health Veterinarians Rabies Compendium. Proof of vaccination must be provided via a rabies vaccination certificate signed by an attending, licensed veterinarian. Mississippi Law requires all dogs and cats to be vaccinated for rabies, using three (3) year vaccine following Rabies Compendium guidelines. For purposes of entry, Mississippi will accept manufacturer recommendations but animals must comply with the three (3) year immunity vaccine requirement if staying in the state or if the animal requires a booster to remain current. Dogs, cats, and ferrets under three (3) months of age may be admitted without rabies vaccination to be quarantined until vaccination at three (3) months of age.
