Gabe's last full body shed was in late August and it went smoothly as always. His spikes normally come off very easily and in sections of 5+. In September I noticed his spikes were looking strange, like maybe he was going to shed, but nothing happened. I started bathing/soaking him every so often, but his spikes continued to look a little off. A couple weeks ago I got him a larger humidifier to help with the humidity in case that was the problem. There has been no change in behavior or appetite. I handle him everyday and this strange yellow stuff appeared in the time I was gone for work, about 8 hours. Any ideas? Should I get him to a vet?
