I apologize if it doesn't work, you might have to go into the project and change the backdrop (it should be the first option that is there) and reset the cats and then press play. Go to the original project. it was terrible but that was because I was just a little person and I tried not to change too much, I still wanted it to be bad but not as terrible as the first one! lhttps://scratch.mit.edu/projects/407665253/
