Why is my hamster screaming and moving strangely while sleeping?

I have no idea why he would vocalize in that way unless he was scared or injured. Any place he could have gotten a leg stuck? He may not have an external injury but that incident could have scared him. As for dreaming, no one knows if they do but, to my knowledge, that has not been documented. I suggest you just monitor him closely to see if it happens again. If it does, you should consider taking him to a vet for an exam.

Thanks for reaching out about Lucy. If the sounds appear from the respiratory system, respiratory congestion is possible. This could be a primary pneumonia or congestion from heart, renal or liver disease. A veterinary visit is needed to diagnose and prescribe a treatment plan. Good luck.

It would be hard to say without an exam, however respiratory issues usually result in symptoms such as raspy breathing, coughing, sneezing, wheezing and changes in behavior including loss of appetite, lethargy, etc. Squeaking on its own doesn't really indicate this, however if you are concerned, or Bolletje is showing symptoms listed above, a vet visit is best. Until you can get her to your vet, keeping her warm and eating and drinking may help, but if symptoms worsen, seeking care sooner is needed.

If you heard a sound in the middle of the night just a single time, and nothing else has ever happened before, I don't think there is anything to worry about just yet. If this happens again, you might want to consider setting up a camera or something while you are sleeping so you can review exactly what is happening. For now, I think you should operate under the assumption that either there was some dream activity, or Pippy maybe just bumped himself on something causing some discomfort. Hope this helps!

I’m sorry to hear about this with your hamster. As you mentioned, 2 is quite old for a hamster so we have to take that into consideration. His increased vocalizations are likely due to discomfort, probably from his illness. I would recommend taking him back to your veterinarian for a recheck just to make sure nothing else is going on. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

It sounds like Red may be having seizures. Make sure he is eating and drinking normally. If he continues to do this then I would recommend to contact your vet for an exam to ensure there is nothing wrong that could be causing the seizure like low glucose, an infection, diabetes, and more.

This most likely is a behavioral characteristic. I would recommend separating the hamsters and seeing if this stops or changes the behavior. I would also make sure that all the hamsters are getting along and the one making the noise is not getting picked on. IF it continues a vet visit is best to make sure there is no underlying disease or pain causing the noise. hope that helps and thanks for using pet coach
