As far as I know, the cost of ultrasound for cats will vary from region to region and from hospital to hospital. Generally speaking, the cost for cats to do B-ultrasound is between 200-500 yuan, and the specific price depends on the hospital equipment, the situation of cats and the items that need to be checked. Some hospitals may also provide some packages, including a series of inspection items, and the cost will be higher accordingly. It is suggested that you can contact the local veterinary hospital or pet medical institution to find out the specific price and service.
