According to the relevant regulations of Beijing, pets, including pet cats, are generally not allowed in public places. Therefore, if you plan to go to Fengtai Fangzhuang Sports Park, it is recommended not to bring pet cats in. If you really need to take your pet cat out for activities, you can choose some special pet parks or pet theme places, but you also need to abide by the regulations and requirements of the places to ensure the safety and hygiene of yourself and your pets. It should be noted that if you bring pets in public places without authorization, you may be dissuaded or punished, which will affect your travel experience.
