Are rabies shots mandatory for indoor-only cats? I live in Maryland, and another round of vaccinations is coming up for Pan....I just hate pumping him full of vaccinations if they are not necessary or required, due to him being pretty low-risk(indoor-only, single cat). He is in the middle of his FCRVP series right now, and when he goes back mid-Feb it will be time for him to get his rabies vac. Just seeing if anyone knows what the requirements are in MD....thank you!
