Squeaking or Chirping
Rats often emit high-pitched squeaks or chirps, especially when they are young or in distress. These noises can indicate excitement, fear, or pain.
Hissing or Growling
Rats may hiss when they feel threatened or agitated. This noise serves as a warning to potential predators or other rats to stay away. Sometimes, rats may combine hissing with low growling sounds to display aggression.
Bruxing
Bruxing is the grinding of teeth that rats do as a form of self-soothing or contentment. It produces a soft grinding or clicking sound and is usually a sign that the rat is feeling relaxed and comfortable.
Chirping or Chattering
Rats may chirp or chatter quietly as a form of communication with other rats. This noise can be heard during social interactions or when rats are exploring their environment.
Scratching or Rustling
While not vocalizations, the sounds of rats scratching or rustling can often be heard as they move around in their habitat or nest. This noise is caused by their sharp claws as they climb or dig.
Ultrasonic Vocalizations
Rats also produce ultrasonic vocalizations that are beyond the range of human hearing. These high-frequency sounds are used for communication between rats and can convey information about their social status, reproductive readiness, or distress.
