Pigs are great animals, they eat virtually anything, dig up the ground, produce great manure and are really fun animals. The only problem with pigs is the feed. Normal domestic pigs eat loads and without harvesting grain, pigs are prohibitively expensive.
The solution to all the problems is a mini pig! These pot belly pigs grow only to 50 kgs and they don't need lots of food whilst providing all the benefits of pigs. Zolibacsi also has a continuous source of reject vegetables which will keep these pig ticking.
