On the whole, Brian is the first choice. First of all, because the use of drops is recognized as a convenient and safe form, Blaine uses a needle tube and will not drip on her hands. The use method is to push the hair on the cat's neck and push the liquid medicine to drop on the skin. The liquid medicine will interact with sebum in vitro, and play a role in vivo through transdermal technology, so as to achieve the purpose of preventing and treating parasites in and out of the body. Second, because it belongs to cats, it is the most widely used insect repellent spectrum on the market at present. The range of insect repellent includes fleas, flea eggs, ticks in vitro and roundworms, hookworms and tapeworms in vivo. These are common parasites, with or without them. Cats will not be at ease unless these parasites are stopped in the cradle. Third, because the brand is more at ease, it comes from the same manufacturer as Fu Laien, and it is one of the cat repellent drugs recommended by the pet hospital. Once a month is safe and secure.
