Hi Connie,
I’m unclear what vaccine your veterinarian might be referring to. Many viruses are species-specific or have some variations between cats and dogs, though rabies knows no boundaries. Cats generally get 2-3 vaccines – FVRCP, Rabies, and maybe Feline Leukemia. Other vaccines exist but are generally not recommended. You would need to clarify further with your veterinarian.
Best of luck,
Dr. Ryan Llera
