Just a random wondering really. Was chatting to a friend of mine who said that some of the horses at the yard she keeps hers at got lice. She said they were 'hay lice' and came in with the hay. Now I was under the impression that lice are contracted animal to animal and couldn't survive without a host. It could just be a miscommunication due to her being Dutch and us speaking English but is there any bug that the horses can catch from hay that is like lice?
So if anybody could clarify that would be great
