Does being eaten by a cat effect gerbil fur growth?

my gerbils had babys a month ago and theyre a month old now and one of the boys has a bald spot will he die? can i help him? he did get slobbered all over by my cat (dont know how this happend i close the cage all the time) before he even opened his eyes and i thought he was but i warmed him up and dried him by rubbing him and rubbed him all over the other gerbils too so he didnt smell like cat slobber and they accepted him, would being eaten by a cat effect gerbil fur growth???
