Getting their veggies is not a quick affair. It drives my wife crazy sometimes. I go over each item carefully to make sure it's cleaned and any wilted or otherwise bad parts are trimmed off. When I have to travel and leave them in the care of family, I make up all of the vegetables they'll need while I'm gone and put them into Ziploc bags with names and dates for each piggie. I'm almost obsessive about their food. I think it comes from losing Scruffy to digestive system issues.
Whatever the reason, these little guys enjoy their food and I enjoy providing the best for them. That's why I put in the time and why I decided to try and grow fresh things for them to eat.
