Pet Obesity Symptom Guide | What to Watch For and When to Seek Veterinary Care
Understand possible causes of obesity and key at-home observations
Non-urgent. Regularly record weight, diet, and activity for assessment.
What this symptom means clinically
Obesity is the excessive accumulation of body fat when energy intake exceeds energy expenditure, accompanied by enlargement and proliferation of fat cells. Adipose tissue is endocrinologically active and releases pro-inflammatory or metabolism-related factors that can affect insulin signaling, metabolic regulation, and organ workload. Clinically, it may appear as a widened body shape, ribs that are difficult to feel, and loss of a visible waist.
🐱 In cats
Cats often gain weight gradually because of indoor living, reduced activity, or overfeeding, and coat color or hair length may hide body-shape changes. Changes in a cat's body condition are often not noticed promptly by owners.
🐶 In dogs
Dogs are more prone to weight gain after neutering and when activity decreases. Fat distribution and the rate of weight gain vary by breed and body type.
