Feline Gastrointestinal Foreign Bodies Study Guide

Gastrointestinal foreign bodies represent one of the most common surgical emergencies in feline practice. Unlike dogs, cats have a distinct predilection for linear foreign bodies such as string, thread, dental floss, and tinsel. This comprehensive study guide covers the pathophysiology, diagnosis, and management of feline GI foreign bodies for NAVLE success.

Key Clinical Points

S.T.R.I.N.G. Memory Aid

S = Sublingual examination always  |  T = Thread most common  |  R = Radiographic plication signs  |  I = Intestinal bunching mechanism  |  N = NEVER pull on string  |  G = Gastrotomy plus enterotomy often needed

Pathophysiology

Why Cats Are Uniquely Susceptible

The feline tongue is covered with backward-pointing papillae (filiform papillae) that act as barbs. When a cat contacts a linear object such as string or thread, the papillae prevent the cat from spitting it out — the only direction available is to swallow. This anatomical feature explains why linear foreign bodies are dramatically more common in cats than dogs.
