"Η γάτα τρώει το πουλί."

[sondernomi]

I don't know if this was mentioned before , but '' πουλί '' also means ''penis'' in greek slang.

Do Greek men have feathers down there?

This curious phenomenon apparently occurs in several European and Asian languages. English and German come to mind.
I don't know why ¯_(ツ)_/¯
As a side note, "πουλί" used in this way is more diminutive than vulgar, I'd say.
