Learn about your cat's body condition score

Understanding how to interpret a cat's body condition score is very useful as a pet owner. This will help determine if your cat is under or overweight and can help guide conversations with your veterinarian. Only weighing your cat without assessing a body condition score may lead to inaccurate results about their health. A body condition score can provide you with additional information and it concentrates on the look and feel of your cat.

How nutrition can support your cat's weight

When it comes to achieving and maintaining a healthy weight for your cat, making sure they receive a nutritionally balanced diet is essential. Rather than simply restricting the portion size of their existing food, feeding your cat a tailored diet with targeted nutrients will help support their body.

Your veterinarian will be able to recommend a nutritionally balanced diet for your cat and an appropriate daily food intake, based on their energy needs and current weight.

Using a body condition score can help you determine if your cat is under or overweight. If so, you should take your cat to your veterinarian. Learn why a body condition score is used and how to find out if your cat is underweight or overweight.

Effective in controlling begging

During a clinical trial, it was found begging was controlled in 82% of cats when fed a Satiety Support dry diet. As the products within the range promote a feeling of fullness after eating, cats may be less likely to beg or feel the need to eat spontaneously throughout the day.

Alyssa is the owner of Pippa, a neutered, female cat.

"The Royal Canin Satiety Support diet is very palatable and well tolerated by my cat. She absolutely gets so excited when I go to feed her and she doesn’t cry and meow between meals on this diet. I chose this diet because my pets have always loved their foods and I love that Royal Canin provides an array of quality diets".

Brittany is the owner of Meeko, a neutered, male cat.

"Meeko, our indoor cat, slowly started becoming overweight. We switched to Royal Canin Satiety Support in hopes that he would not only lose weight but stay full. He was 11.5 lbs at his heaviest and has gotten down to roughly 9 lbs, a healthy weight for him. With Satiety Support, he seems to stay full and he no longer cries for food in the middle of the night. He seems to really enjoy this diet."
