Train?!? Sows are usually slightly cleaner in their litter tray habits but boars can be more cuddly than sows.
They are both equally good at training us to serve them using their cute looks and lovely wheeking.
My pair of sows rarely pee on theirnfleece area, preferring to use their litter trays but they poo all over the place. My young boar poos and wees in selected areas of his cage, not necessarily in his litter tray ...
They are all utterly wonderful and lovely and cute and worth every poo picking and fleece washing moment!
