You can use any of these sprites for your projects.

Notes and Credits
These are the Scratch Cat sprites from the animation "A Day In The Life" by @ScratchCat: https://scratch.mit.edu/projects/153352092/
I just removed the text and other sprites, so you don't have to.
I personally like these more than the default sprites.
TurboWarp is a Scratch mod that compiles projects to JavaScript to make them run really fast. Try it out by inputting a project ID or URL above or choosing a featured project below.
