Y take out the cat? , it's there for a reason and dat is to keep noise pollution and air pollution as little as possible, now by taking off that, U create as much noise and air pollution as possible, I don't know about u but if everyone as self-fish as u takin their cat or whole thing off, then i guess we'll die in no time.. It's there for a reason mate. And surely if u don't have it, I will be extremely happy to c u get stop by cops
