Kittens over a month need to pay attention to eating less and eating more meals, vaccinating regularly, expelling insects regularly and so on. First of all, eat a small amount of food several times a day to prevent kittens from vomiting due to excessive intake of cat food at one time. Secondly, when the cat does not have symptoms such as coughing and sneezing, it should be taken to the pet hospital for immunization in time to reduce the chance of the cat suffering from infectious diseases. Finally, regular deworming to ensure the health of kittens.
