A few common questions
Can this tool tell me my cat's ideal weight?
It provides a rough estimate when you know the body condition score. Your vet can confirm a suitable weight after considering muscle, age, breed and health history.
Is it safe to reduce food quickly if the score is high?
No. Cats should not crash diet. Use the result as a note for a veterinarian or a gradual feeding review.
