AstroCat-based catalogs are intended to hold information on the physical properties of astronomical objects of a specific class. The catalog is interactive in that it allows registered users to add new objects, and the quality is monitored by editors. Changes are instantly visible guaranteeing an up-to-date version. A restoring mechanism ensures citability. It also provides a powerful search functionality. We will present the CVcat as an application and also offer a demonstration of AstroCat.
