sibilant

SIB-ih-lunt/ˈsɪbɪlənt/

A hissing sound like s or sh, or having this sound.

The cat's sibilant hiss escapes through bared teeth as its back arches.

A defensive cat caught mid-hiss: flattened ears, wrinkled muzzle, exposed teeth, low tongue, arched back, and puffed tail reinforce the recognizable hissing sound rather than an ordinary meow.
Etymology

The Latin pieces mean “hissing,” describing the audible quality shared by sounds such as s and sh. The verb sibilare may itself have arisen as an imitation of hissing or whistling.
