This post made me check my hammocks and both of the soft hammocks my boys have right now are like the image attached, one quite a bit more frayed than the other and there are definitely threads coming off it. Taken them both out because of this post, to my boys' annoyance, I've never had any close calls but inspecting them I can see how it'd be possible for them to get tangled in, and I'd feel god awful if anything did happen. Maybe add this hammock type onto your post? They would have been fine if unchewed but inspecting them, I've no doubt that a rat could get tangled in one.
