The British shorthair cat of Sister Zhen's family you mentioned is actually a British shorthair cat of the Douyin blogger, the kitten is chubby and very cute when walking.

British shorthair cats are bold and curious, but very gentle and adaptable. They will not change due to changes in the environment, nor will they lose their temper or bark. Try to climb to a higher place, staring down at the big round eyes looking down at you with a smile, just like the one mentioned in Alice in Wonderland is called “Louis”Like a cat, no words, just with that cute facial expression grabs your heart, and can no longer change your love for it.
