Living Word Bird Iodine Block. Choice of formats.

Calcium and iodine deficiencies are common in caged birds because these vital nutrients are missing from some staple foods. Living World Iodine Block contains essential minerals not found in seed diets and helps prevent mineral deficiencies.
Enriched with calcium and phosphorus, the iodine block is a beneficial dietary supplement for all caged birds. Iodine Block helps prevent weak bones (calcium deficiency), enlarged thyroid gland in budgies (iodine deficiency), egg retention (calcium deficiency) and tremors.
Built-in clips make it easy to attach the block to the bird's cage.
