How to measure your cat?

Each cat is unique in size, select the size with the closest measurements. To ensure accurate measurements, make sure that your cat is standing properly, not sitting or lying down. Use the size chart below as a guide. We recommend using a fabric measuring tape when determining your cat’s measurements and allow some leeway to ensure a comfortable fit. If you do not have a fabric measuring tape, use a shoelace or any other string and measure it up against a ruler.
1. Chest: measure the widest part of the chest, which is usually 1-2 inches or 3-5 centimeters behind his/her front legs.
2. Length: measure along his/her backbone from the base of the neck to the base of his/her tail.
3. Weight: if you do not know the weight of your cat, weigh yourself holding and not holding your cat. Subtract the numbers, and now you have your cats weight.
