I've had my rabbits for about 4 weeks and they're around 4 months old, they have had all there vaccinations and such and had there last set a week ago. I started to notice clumps of fur in the cage with what looks like dead/dry skin on it. I knew exactly which rabbit it belonged too because they're both different colours. I checked her over and noticed what looks like dandruff and slightly bald spots (I will try to attach a photo) could this be anything serious? Does she need to go back to the vet? Is there anything I can try before hand? Help!
