The pet column “Animal Island,” in which Marc Morrone answers readers’ questions, is being discontinued. A Newsday review of past columns has found that some previously published questions and answers have been reused and that names and communities for some questioners could not be verified. When asked about our findings, Morrone confirmed he repeated column material and said he created names and towns for some columns. Newsday will be bringing readers a new pet column, “My Pet World” by Cathy M. Rosenthal, which will appear Tuesdays in Explore LI.
