Any species can get this, but we most commonly see it in cats.

Cats love to play with string or yarn, and in some cases they end up swallowing it. As the string passes into the intestinal tract, one end often becomes lodged around the base of the tongue, or the exit of the stomach. The rest of the string will flow freely down the intestinal tract, until the entire length of the string is uncoiled within the abdomen.

Having a long, immobile string in the intestine is pretty bad news! The intestine constantly contracts to push food along. When it contracts on the immobile string, it ends up bunching up in a characteristic pattern called ๐ฉ๐ฅ๐ข๐œ๐š๐ญ๐ข๐จ๐ง. In some cases, these pleats are so tight that food is unable to pass through! The contraction of the intestine against the string also damages the intestinal wall, and eventually may cause it to rupture.

The typical method of diagnosis is X-rays, which show the bunching of the intestines into a big ball. Ultrasound is also helpful to identify plication.

The only real treatment is surgical removal of the string!
