In life, cats drink too little water, suffer from severe indigestion in the intestines, slow intestinal peristalsis causing feces to stay in the intestines for too long, excessive water absorption, etc. These can easily lead to cats not pooping and causing constipation.

At the same time, cats suffering from lumbar spine disease are afraid to defecate due to pain; or the innervating nerves and defecation center cannot be controlled after damage, causing constipation. In addition, if the fiber content in cat food is too low, it can also cause constipation. In older cats, constipation is also associated with megacolon.
