A:Hair Loss in Pet Rat PetPlanet Vets PPAdmin email@example.com
It seems a little odd that just one of your rats is affected with the problem. However it is always a good idea to eliminate possibilities. She has been treated for mites (presumably using an injection at the vets?). Were any of the other rats also treated or was it just her? The other rats
may be harbouring a problem without showing signs. The fact that you saw another rat grooming her and hair was coming out may
be an important point. Grooming, or over grooming, often leads to hair loss
and so this may be the reason for the hair loss. Is the rat well in herself? Is she bright, with a normal appetite? Has she lost or gained any weight? If she appears healthy, then it may be that the baldness is a behavioural or social baldness due to interactions between the rats where she is being groomed by other rats. This would not be a serious problem so long as it did not become a form of bullying. It may be helpful to check the weight of this rat (and all your group) regularly to see if there are
any changes. If she is stressed by the grooming attention then she is likely to begin to loose weight. If she seems unwell in any way then you should talk to your vet again. It may be that she is sick in some other, possibly serious way, which means that other rats are tending to groom her. Angela Bodey MRCVS (Vet for PetPlanet)
