Mice make noises when they are in pain

Mice make noises!

Hello cat man,
There is basically only one explanation for the behavior of the mouse that you have observed. Mice don't moan or cackle and they don't talk to their owners either. Mice communicate with each other in a frequency range that is inaudible to human ears. You can only hear the screeching of fear or the screeching during an argument. Then there is a cleaning beep with which the mouse signals to its conspecifics that the cleaning is too hard. All other noises are pathological and are usually the expression of mucus in the airways, as we know it in human medicine, for example in asthma ("wheezing, whistling, thumping"). The "chattering", "moaning" or also "chirping" and "rattling" are very likely an expression of bronchitis, which one must count among the respiratory infections. The different frequencies depend, among other things, on the respiratory rate and the current diameter of the airways. The mice are excited when someone deals with them and they actually show preferences or reservations about certain people. This then explains the variation in breathing sounds.

Unfortunately, color mice are prone to tumors as well as respiratory infections. In contrast to humans, only few useful diagnostic methods are available for mice (X-rays are usually only possible under anesthesia, blood tests are usually not carried out due to the small blood volume), so that one can usually only orientate oneself on the clinical symptoms. If, in addition to breathing sounds, the mouse has a shaggy, fluffy fur, reduces food consumption and flank breathing occurs, then one must assume that the bronchitis has turned into pneumonia, which is then an emergency, since the small mice develop pneumonia within can die within a few days.

For this reason, respiratory infections in mice are usually treated with AB. It makes sense to record the noises before visiting a veterinarian with the mouse, as many vets do not have much practical experience in treating mice. The most common AB, which is very well tolerated by mice, is Baytril (enrofloxacin). In addition, an expectorant (e.g. bromhexine / bisolvon) can be given. The best of these is the injection solution, which can also be administered orally.

Following this part of my answer: Welcome here in the forum!
As a rule, all questions are read in full here, otherwise they cannot be answered meaningfully.
If you have any questions, please!

Epilogue: Unfortunately, I can't help but add a comment about the breeders. The term "breeder" is not protected as far as the reproduction of mice is concerned, there are no guidelines for breeding mice and the breeders are not monitored by any authority. Anyone can call themselves a "breeder". The people in this forum are not very "popular", mice are mass-produced and many animals bought in pet shops end up in animal shelters and foster homes. Many users here regularly go to the TH, have billy bucks castrated at their own expense and then look for suitable end-of-line locations for the animals, while at the same time new animals are constantly being "reproduced" by breeders and animal shops. There is a "mouse misery", mostly invisible to the normal consumer, in pet shops, back rooms and also in the enclosures of mouse owners. We have decided here in this forum to counteract this and improve the situation of the mice wherever possible. So to educate a little bit about keeping mice. Sorry! So here's a little hint: Mice are actually group animals that only really feel at home with many conspecifics. They also like to sleep stacked - if possible under, over and to the right and left of them, also a mouse! For the minimum size of a group, 4 mice are recommended. If one of your mice dies, there will only be two mice left. Then at the latest it is time to think about increasing the group (please then socialize the mice according to all the rules of the art). Maybe animal shelter or foster home mice will also get a chance? No bad feelings!

Edit: If you are interested: Mäuseböckchen actually advertise for their partner with a kind of "song", but also in frequencies inaudible to human ears. Simply enter "Mäusegesang" in google! Scientists have made this "courtship song" audible by slowing down the frequencies, among other things.
