Standard Slingshot Ammo - Plentiful and predictable, this slingshot ammunition will reliably return cat food to the safe and comfortable surface of the Earth. Pull back and release! Big Bertha Slingshot Ammo - This depleted Uranium orb will obliterate even the most resilient construction materials. When steel blocks are keeping cat food out of reach, turn to the Big Bertha. Laser Ball Slingshot Ammo - Affectionately known as "The Disintegrator," this tiny sphere pacts a horrifying punch that will eliminate and single obstacle upon contact. Use this ammo if you can identify a key block in the obstacle you are facing, and removing that piece will bring the whole thing down. (Not so useful against steel, though...) Shotgun Splingshot Ammo - When there are just too many cats to feed and just not enough ammunition... The shotgun round turns into 6 smaller rounds. It doesn't have the power of the other specialized ammunition, but it can take down a host of fragile supports without breaking a sweat. Explosive Slingshot Ammo - By far the most fun, the explosive ammunition also has a practical applications. It is the skeleton key, the open sesame, the result of years of painstaking research. Use it in good health. Regular Blocks - Just like the ones we have, the regular balls can knock them down. Steel Blocks - Heavier than the regular blocks, resistant to Laser Balls, and too heavy to knock down with regular balls. Heavy ball is great for them. Concrete Blocks - Even heavier than the Steel blocks, heavy balls don't work as well, but are vulnerable to explosive. Glass Blocks - They don't just fall, but break up when hit by things.
