Hmm, if it was a large order I would send back the ones that obviously have an issue, and put the seller on notice that if anything else develops those weird markings you will be sending those back as well.
I think the Catts look OK. As I said in the other thread they tend to look kind of ratty anyway. I would keep all of these new ones away from the rest of your collection until you are reasonably sure they are free of pests and disease. You won't know if they are virused unless you test.
Have you ordered from this grower before?
