!Lag Warning! Press the Green Flag to Start. Press space to make cats. Cats variable: How many cats on the screen. Creation variable: How many cat created while holding the spacebar per frame (move the slider to change this number). FPS variable: How many frames per second there are (updates once a second). Don't worry about the clone limit of 300 because this project only uses 1 sprite, the pen function, lists, and My Blocks to create potentially thousands of cats on the screen instead of just the regular 300. However, the project may start to break past 10,000 cats because all the loops cause the game to lag to the point it needs more than a singular frame to render all the cats.
This took me a few days to make. Code by me. Scratch was found in the Scratch Library. You may use this as an engine in your projects.
