Chipper is an excessive licker, especially blankets. I go through bottles and bottles of Bitter Apple. Every time I wash a blanket or bed I have to spray. One of the consequences of licking blankets is that he has a lot of thread fibers in his stools. My vet told me to give him CatLax to help. I found this article and plan on checking it out with my vet.
