What Causes Abdominal Distension in Cats?

Abdominal distension in cats can signal anything from benign indigestion to serious congenital defects such as anal atresia or polycystic kidney disease. Dietary causes include spoiled ('toxic') milk from an infected queen, while parasites, infections, and simple digestive upset are common culprits. Because bloating ranges from mild to life-threatening, prompt deworming, probiotics, or a veterinary diagnosis is essential.
