If your kitten suddenly becomes lethargic and is always lying there sleeping, it might be due to the following reasons. First, the kitten may have symptoms of anemia. Anemia has always been a problem for kittens because of insufficient nutritional intake, which causes the kitten to be lethargic and in a state of low energy for a long time. To address this problem, it is necessary to ensure a balanced nutritional diet.

First, for feeding cats, they must intake enough protein. In daily feeding, this can be addressed by some high-protein cat food. In this way, the cat can intake higher protein for nutritional supplementation, which can alleviate the symptoms of anemia. During the feeding process, it is also important to intake some appropriate vitamins. Many people may have misunderstandings about kittens, thinking that kittens do not need to eat cooked vegetables. However, within a balanced nutritional system, cats need to intake some vegetables because they contain rich vitamins that can help the cat's hematopoietic cells continuously provide fresh blood. During feeding, it is also appropriate to give kittens some blood-building paste, which can achieve the purpose of blood formation.

Besides anemia, there are other issues, such as cats having a cold or some flu-like illnesses. These flu-like diseases can also cause cats to be lethargic and lie in one place sleeping for a long time. At this time, a thorough examination should be conducted to ensure the cat remains lively during this process. Because many diseases can directly cause death in cats, prolonged lethargy signals the arrival of many illnesses, and it might also be caused by the cat’s own lack of exercise.

Therefore, if you find your cat has any illness while raising it, you should promptly take it to the hospital for examination and treatment. If it is due to lack of exercise, you can increase its activity by taking it out for walks and so on.
