anyone remember that rat breeding game?

Hey all,

I remember back in 2019/2020, there was a website where you could play this game and you buy/sell/trade/breed rats and I can't remember what it was called. but it was so fun!!

idk if it's still around but any help would be appreciated! I need to relive the memories🥹

UPDATE: I did more digging and it was called virturatz! it was so much fun but I cant find the website anymore
