i'v been hunting these critters for 12+years and have learned a lot. i have one living in my front yard shrubbery and he/she is my teacher. it comes out to eat in the afternoon and does so every other day. if it sees me in the window, i'll freeze and after some staring, it resumes eating. i'v watched a field with 20+ holes and one will appear one day and not another, while others come out of the other holes with the same pattern. do they sleep and ? in their dens for 24+hours? some are regulars but seem to nibble and run, esp the barn pigs. some just stare at me and others vanish instantly. some are climbers and some take naps on rocks/logs routinely. climbing seems to be inherited...shot 4 off the same fence post during a season. finally, their diet. always felt they loved alfalfa, clover, fruit,etc. but watched my shrubbery pig eating GOAT TURDS! it did cleanse it's palate with clover later. yuk.
