A fluid delivery system for a pet includes a reservoir for a fluid and a fluid delivery assembly connected to the reservoir. The fluid delivery assembly includes a fluid release roller, a housing encasing the fluid release roller, and an engagement surface mated with the fluid release roller to create a fluidic seal in response to static pressure upon the fluid release roller from the fluid. The fluidic seal is released to allow a flow of the fluid in response to dynamic pressure applied to the fluid release roller by a pet.
