We have a male and female hog moved into our pen and are very amused by the friendliness of one of them, not at all shy, will approach a person, has explored the whole pen and eats a full pouch of wet cat food & kitten biscuits every evening/night! It will happily let you stroke it. (We have to figure out which is male/female!) The other hog is a little shyer and comes out in the late evening/night to eat scattered kitten biscuits mainly & drink. They have packed their hibernation home with even more hay & seem to love it in there! We are seeing lots of activity 🙂
