i don't really know about the particulars of that seed but all seeds should be kept in a treat capicity only. they have high fat rates and most are high in protein. just a few of them could case an overdose in protein which isn't deadly but certainly irrating to the rat when s/he is so itchy that scabs can appear and high loss can occur. i know peanuts will destroy vitamin A but they're still ok as the occasional treat. i imagine that honeydew seeds would be in the same catergory, ok in moderation
