The same. The Present Simple/Continous difference is not present in Polish.
Having said that, there are some verbs that are used for 'habitual' actions, and there's verb 'jadać' which means exactly that for eating. So a better option for "My cat eats meat" (generally) could be "Mój kot jada mięso". It would work even better if the sentence was "my cat doesn't eat meat at all". But we're not teaching it, and simple "je" is enough here.
Jellei, first of all Dziękuje bardzo for all the great explanations and for this site! Since you are talking about the tree, my question is: when I first entered duolingo, I could "buy" with the lingots 2 different skills, which were Proverbs and Love. Latter I came back (because I'm currently in Poland) and those skills had desapeared. Why? And since then I am waiting for something to do with the lingots (like "buying" extra skills or stories) but... Nada. What can we do with the lingots then?
Yes, I don't believe there were ever any bonus skills for Polish.
In fact, the functionality of creating bonus skills has been broken for years and is apparently really complicated to fix for the devs, so it's not coming back soon. Only those that already exist (for the most popular languages, as you said) are in the trees.
Ok, maybe I made confusion and tryied german, long ago... Ill check. But it was a nice idea. So what are the lingots good for? We could "buy" some vocabulary... I'm in Poland now, and the vocabulary they like to teach me is... Very funny for them when I repeat. Like... K... Pier... Etc. I'd better stick to your vocabulary for work purposes!
