The fluid distribution cage has one or more arms connecting an upper plate and a lower plate. The lower plate is configured to direct fluid sprayed onto it from the fluid delivery tube. When fluid is sprayed on the lower plate the upper plate begins to nutate around the fluid delivery tube between the upper sprinkler body plate and lower sprinkler body plate. The upper and lower sprinkler body plates have races configured for receiving one or more resilient cushions positioned on the upper plate of the fluid distribution cage. The upper cage plate or the lower sprinkler body plate has one or more projections positioned such that the fluid distribution cage hangs at an angle to facilitate initiation of nutation of the fluid distribution cage.
