Is my cat too fat or too skinny? A guide to body condition scoring in catsHave you ever wondered if your cat is an ideal weight? How do you know if you need to cut out on some of the treats? It is important to keep your cat an ideal weight throughout their life to prevent diseases such as diabetes and arthritis. When vets assess your cat’s weight they are not just looking at the number on the scales but also assessing something called Body Condition Score (BCS). This is because the genetics of every cat are different and the overall condition is more helpful to assess what the ideal body weight for your cat is. Our vet shares their tips and advice here.

If you have a very fluffy pet, think of how they look in the bath when their hair is all wet. Learning to body condition score your cat will help keep them healthy at all life stages.The four main things we assess when deciding on overall body condition are:Ability to feel ribs, lower spine and bony prominencesAbility to see a ‘waist’ - tucking in of the abdomen after the ribcage when looking at your cat from aboveAbility to see an ‘abdominal tuck’ - tucking up (upward slant) of the abdomen after the ribcage when looking at your cat from the sidePresence of fat depositsA body condition score is the score given to your cat (out of 9) depending on which of the above features you can see and feel. Make sure to run your hands over your cat to assess the amount of fat you can feel over the ribs and spine as well as look at your cat’s silhouette from above and from the side.1-3: Under ideal1 - Ribs very easily seen on short-haired cats.
