oh jesus no.. ball pythons are a snake that are going to average out at 4'-6' pinkies are tiny balls of fat that offer little nutritional benefit! ball pythons from the egg for me eat live fuzzies then you just judge their meal size by the biggest point (girth) in their body. dont worry, they wont choke, all snakes jaws are made to unhinge to match the size of their body. Kenyan sand boas are on pinkies for the first year, then they move up to fuzzies and small hoppers within the 2nd & 3rd year (depending on how fast they are growing) you should NEVER EVER feed a ball python or a kenyan sand boa pinkies for life, if you try that you shouldnt own snakes in the first place. NEVER BE STINGY PAYING FOR SNAKE FOOD, cause you should've thought of all that the snake is actually going to require before you bought it. You can, however, try feeding frozen-thawed food for the ball python, but it still is going to have to be , hoppers, mice and eventually rats. kenyan sand boas, are going to have to do live though because they are a ground dwelling boa, they rely on the vibrations of thier prey on the surface, a frozen lifeless meal wont do that. Their eyesight is terrible, hence they use their incredible vibration senses to track down food. So for your ball python, you can try a frozen-thawed hopper, and your kenyan sand boa, im afraid your gonna have to stick with live.
