"Recent laboratory results show that the products contain melamine. We believe the source of the melamine is a rice protein concentrate. Natural Balance has confirmed this morning that some production batches of these products may contain melamine." http://www.naturalbalanceinc.com/press_release.html I just did some research on MELAMINE and apparently ingestion of this chemical substance can cause kidney stones, cancer, or reproductive damage. Jemma's been on this food for about a year and a half now. Should I be concerned? Should I bring her into the vet to get any tests done?
