🛌 Why Is My Cat Lethargic? 2025 Vet Insights 🐱

Hello caring cat parents! 😊 I’m Dr Duncan Houston BVSc. If your cat seems unusually quiet, uninterested, or sleeps much more than normal, they could be lethargic—a sign something’s off. This guide explains how to spot true lethargy, potential causes—from mild illness to emergencies—and how Ask A Vet can support timely, attentive care so your feline companion regains their spark.
