Some people may misunderstand that the depressed sternum of cats is a health problem, but it is actually a normal physiological structure. When you touch this prominent part, you don't need to be too worried or nervous. Only when the cat's sternum is obviously prominent and accompanied by other symptoms, such as cough, vomiting, dyspnea, etc. It is necessary to take him to the vet.
If you notice that your cat has difficulty breathing or abnormal behavior, especially after activities or when the weather is hot, it may indicate that the cat's tolerance to temperature and exercise is affected. In this case, some changes can be taken according to the veterinary advice, such as better management of indoor temperature, less exercise and diet management.
In a word, the chest depression of a kitten is a normal cat body structure and does not need special attention. If there are other abnormal symptoms, it is recommended to seek medical advice in time.
