Step 1 : Introduction to the question "What is the technical name for a cat's hairball?"
The technical name for a cat's hairball is trichobezoar. A hairball is a lump of accumulated indigestible material, in this case hair, that forms in the cat's digestive tract. Cats have a unique digestive system that lets them swallow and digest fur. This is an evolutionary adaptation that helps the cat get every bit of nutrition it can from it's food, even the fur of the prey they hunt and consume. Hairballs in today's domesticated cats are usually a result of self-grooming. Source: CatHealth.com
