Thanks Jodie, I have seen postings about filing rough edges on the shells and wondered about the edge of the plastron too. I can't say I've seen how other torts walk close up so this they may be normal.I am not sure. It seems like I read somewhere recommending just that, but common sense tells me no. It is bone and has nerves, so it seems like it would be painful and have to heal. @Yvonne G, is this a good solution?
