Those pellets don't sound like they're very good for your pig. You should switch to something like Oxbow Cavy Cuisine, which is a high quality timothy hay pellet. Any pellets with other stuff in them like the banana chips, pumpkins seeds, split peas, carrots, oats, corn, seeds, etc. that you mentioned are not good for cavies. The seeds present a choking hazard and also are unhealthy, as are the other add-ins. Stick to a plain pellet without anything added in. Also, watch the fruit: they need mainly high-quality lettuce such as romaine, with some other vegetables added in. The fruit has a lot of sugar that can lead to health problems.
