adding missing term -- not sure what cat is should go in, maybe someone can suggest
Objects which are '''calcareous''' in nature are composed of or contain [[calcite]] or [[calcium carbonate]]. [[Chalk]] and [[limestone]] are calcareous, being composed of calcium carbonate. Certain groups of sea creatures ([[calcarea]], [[phytoplankton]], and [[sea urchin|sea urchins]] for example) have calcareous skeletal structures, which accumulate on ocean floors, and is a major factor in how [[coral]] is formed.
