What is pica in dogs?

Answer 1

"Pica" refers to ingesting anything that is not a food item. In dogs, some of the items most commonly ingested are rocks, dirt, and clothing materials such as socks. While it's sometimes a mere nuisance- such as with coprophagia, the form of pica that involves eating feces- pica can lead to serious medical problems if a dog ingests a large rock or sock that becomes lodged in the intestines.

Answer 2

Pica means eating non-food items. Cats often chew, especially kittens! But adult cats usually do not have a chronic pica problem.
