I find all of my hamsters make similar noises but for completely different reasons! XD
Thistle sounds EXACTLY like a dogs squeek toy if you make her jump and she makes a quiet clicking noise when she is excited. She also makes a 'Buzz' sound if you put Pippy into her line of site or smell - thats her excited yet scared noise. If she gets as sudden fright she crackles.
Pippy will crackle when she is scared or cross but she never squeeks and if she 'Buzzes' it means shes bored
Truffle and Cookie both chirp like budgies when they are startled or hurt and click when they are nervous but never crackle.
Trevor, Kiku and Jení make no sounds whatsoever :L
