What has been your experience with using the new Standing Heat patches? We put three on a week ago and two of them were off within 3 days. I see they have to be warmed to 100 degrees when applied and pressed on firmly and maybe we need to be more diligent in that part. We've always used EstrusAlert and never had a problem with them coming off. Sometimes they pull hair and hide when trying to remove them. The Standing Heat don't seem to have as much adhesive.
