The 441 drug used by cats is a fast-acting drug for treating abdominal transmission in cats, so the market price of 441 is very high. Generally, regular pet hospitals have a bottle that costs between 1,500 and 2,000 yuan, and one bottle can be used for intravenous drips for about ten days. Breeders can also buy medicine online after diagnosing a cat with abdominal transmission or ascites disease, and the price will be higher. Pet hospitals are much cheaper.
