This is:
The cat has a new joke, I don't know what to do.
ZZZ: What is it?
xxx: He has recently fattened a lot of food, then swallowed and again eats it all!
Zzzz: The food is delicious. And he knows that you won’t give it anymore, so he eats twice the delicious food!
XXX: I don’t do that ?
Zzz: So you’re a stupid man, and he’s a cat.

You are a stupid man, catch the cat’s buttocks and run to the veterinarian! He supposedly has a gastritis starting! And even if it is not, the doctor’s advice is still needed!
