I'm sorry, but I do believe that cats know happiness. So do dogs and other creatures...Anyone agree?
Sure, in general yes, but you haven't seen my cat :D She only knows contempt. And hunger.
LOL! Well, just like people, some cats are just like that. They do have a bit of a reputation for being like you explained. You will be fine.
I wrote "koń" instead of "kot" and it was accepted XD. A cat and a horse are the same animals for Duo here.
I really don't know what to say, but I passed this example further hoping that someone from the company will see it.
(some spelling mistakes in the lyrics)
I wrote This cat does not know what happiness is.
but duo says it's wrong !!!
