  The VLA has been used to image HI in a heterogeneous sample of nine Seyferts
as part of a continuing investigation of the role of galactic host gas in the
triggering and fuelling of nuclear activity. Where previous single-dish
observations indicated complex, poorly understood kinematics, improved angular
resolution and sensitivity reveal tidal tails and intragroup gas, distinguish
dwarfs from main disks and resolve non-linear gas dynamical features such as
shocks in bars. Seyferts may be abnormally gas-rich, but a larger,
statistically significant comparison of HI properties of normal and active
galaxies is now required.
