Frequently Asked Questions
How do I know if my cat is underweight or overweight?
Perform a Body Condition Score check: in an ideal cat, ribs are easily felt under a slight fat covering, a waistline is clearly visible from above, and the abdomen tucks up behind the ribs.
Does neutering cause cats to gain weight?
Neutering decreases resting metabolic rate by approximately 20-25% while appetite increases. Feeding a tailored sterilized cat diet and measuring portions prevents obesity.
What is the weight difference between male and female cats?
Male cats have denser bone frames and muscle mass, typically weighing 15% to 30% (about 0.5 to 1.5 kg) more than females of the same breed.
