hi,
i have gunie pigs and know alot about them !
for # 1.) depends on the gunie pig we had a medium cage and could pick them up by the 2nd day they will still run away but thats how they get used to you
2.)when you start picking them up and giving them treats depends how much u do that !
they live better and longer in packs they should get batha every 7 months ( in warm months heres a website if u need any other info ! ...
