Vaccine-associated sarcoma in cats

Daisy made a very good point in comments, which is that there is a risk of vaccine-associated sarcoma in cats (read more...). It's good for cat parents to know about this risk. Our vet does vaccines in a leg, because that is easier to remove if a sarcoma develops. In our state, a rabies vaccine is required for cats, but nothing else. Keeping your kitty indoors can protect them from FeLV and other communicable diseases. Our cats are all indoors and only go out on supervised leash walks.
