Rabbits are not very vocal but have a range of sounds indicating different feelings:

Thumping of the back feet – this noise is associated with fear and is a way of warning others of dangers in the area. Dominant rabbits will also thump in order to gain attention.

Hissing, growling or muttering – usually indicates aggression and precedes an attack. It indicates the rabbit feels threatened or is behaving territorially.

Teeth grinding – soft grinding or cooing means your rabbit is happy (and often accompanies being tickled or stroked). Loud grinding is a sign of intense pain as is loud squealing – it may also indicate danger.
