Hi. I purchased a yearling gtp female approx 7 months ago from one of the well known breeders about. In the last 5 months she has developed lumps along her spine about 5 inches long upwards from her vent( I cannot upload pic but will keep trying). The breeder informs me he has had other complaints and he also has 2 that have same problem( not her parents). He does not know what is causing this. I have never handled her or my others, she is housed and fed exactly like the rest and they have no issues. I believe its genetics. He says I can breed her no problem but I do not want to pass bad genes along if thats the issue. Do any fellow gtp owners know what this could be. Any help would be appreciated. Thanks J
