Fact checked by a Hello Ralphie expert veterinarian As with people, the average weight for cats can vary depending on their skeletal size and gender. On average, a healthy cat usually weighs between 7 and 14 pounds. In some cases, cats can weigh a little more than this or a little less, so it can be useful to schedule an online vet appointment through Hello Ralphie to determine if your cat is within a healthy weight range. During a Hello Ralphie virtual vet appointment, you and the vet can come up with a healthy nutrition and weight-management plan for your specific cat.
