Not all cats eat every food, some don't like meat, some fish, and some eat cucumbers, and it's fine! Just make sure your cat gets all vital vitamins and trace elements.
What the term “natural” on a pet food label implies: A pet food product that is wholesome and nutritious, and made of whole, unprocessed or unaltered ingredients.
A body condition score (BCS) is a number assigned to your pet based on evaluation of fat at a few key locations on their body. A BCS can range from 1 to 9 (though some hospitals use a 1 to 5 scale). A BCS of 1 means an animal is severely underweight, probably in danger of death from starvation. On the opposite side of scale, a BCS of 9 means an animal is severely overweight, covered in fat, and at risk for suffering from arthritis and diabetes to name a few complications of obesity. An ideal BCS is 4-5 out of 9. For every number above 5, your pet is an extra 10 percent overweight.
