|  | Hamster body LanguageHamsters do  have a language of their own, they communicate mostly by  scent trails  from the hip  spots or  urine. Some of the sounds they make are ultrasonic; meaning the frequencies of  the sounds made are largely out of the range of human hearing. They can hear  and communicate without being heard by humans or potential predators. Some  animals such as dogs, dolphins, bats, mice, and hamsters have an upper limit that  is greater than that of the human ear, and thus  can hear ultrasound. Some appliances  we use daily can emit sound in ultrasonic frequencies that we cannot hear, and this  may explain those sudden moments of anxiety that we see in an otherwise  normally calm hamster. 
 Just like the dog whistle that emits a sound in the upper audible range of  human hearing, we can’t hear it but the dog can. It is also a known fact that  some young children can hear sounds that older people can’t, and a cell phone  company has exploited this to create ring tones supposedly, that can only be  heard by younger humans.
 Some manufactures have also developed an ultrasound  generator speaker system that humans cannot hear, with claims that they frighten  and keep rodents away.
 TVs’ mobile phones and even some domestic appliances can  emit ultrasonic sound when operating.
 
 Occasionally loud clicking noises may be heard. Theses clicking noises are made by the front  teeth rubbing together, this is known as Bruxing,  Some hamster owners'  misinterpret this as a sign of aggression when in fact it has nothing to do with being aggressive. The two incisors in the upper and lower jaw continuously grow throughout  the life of the hamster and normally receive continuous wear as the upper  and lower contact each other when eating normally. Periodically, on occasions you may hear this  clicking noise  when he is awake and stood still; as they rarely do it whilst moving. It may also be heard during sleep as it is a subconscious  behavior. It may also be of interest to know they do it only when relaxed and  content.
 
 No generalization can be made for all the audible sounds a hamster makes and  most of those sounds heard by humans are interpreted mainly as warning sounds  or when the animal is distressed. Sounds that resemble growling, hissing, showing its teeth,  or squealing, simply means don’t touch me. A chuffing sound may be heard when  he is frustrated.
 A young baby hamster that makes a loud screeching noise and occasionally flips  on his back with his paws in the air; this is fright, or the submissive pose. A  newly acquired baby hamster that  is not used to being handled are most  likely to do this when you try to pick them up. See Taming
 
 The visual  signs of body language are stretching and yawning and  the sign of a relaxed  and contented hamster.
 Walking stiff legged with the back arched is mostly done by younger hamsters'  in the presence of older or more dominant hamsters' to express submission.
 Grooming expresses the hamsters well being and contentment. Prolonged grooming  or continuous and liberal face, and body washing, is made when the hamster is  put in unfamiliar areas. The hamster is actually scenting his paws and other parts  of his body in readiness to mark new territory.
 Standing tall on his hind legs ears pricked up and nose in the air denotes  curiosity and that something has attracted his attention.
 
 Hamster Squeaking A hamster  squeaking usually indicates that there is something wrong.But on occasions I have heard them squeak with delight when it is time to come  out and play or he is being groomed by you. Feeding time can sometimes attract  a little squeak.
 But a persistent squeak from him when there is no one around the cage then it  is an indication that something is bothering him.
