One of my guinea pigs had a small scab on their back which has now fallen of. I noticed that on the scab there was some of his fur and there is now a bald patch where the scab once was. It has heeled nicely I'm just a bit worried incase it is symptoms of an infection etc.. I have an appointment at the vets for saturday so i will ask them I'm just wondering if i need to push the appointment foward or not. Thanks
