So I just bought a male Guinea pig and if I am not mistaken it is fairly young judging by its size. I feed and all that but it just stays in its hide spot for ever until it feels it is alone or unnoticed by me (its in my room). I get impatient and sometimes a little angry/frustrated so I force it out of his cage and to be with me but it just freezes up. When I pet its mid and rear section it makes a low squeak kinda sound, to me sounds like it is content but it stops as soon as i stop, also if I make no moves for a while it starts to make a low noise like the latter and it kinda moves around a little and chomps its teeth. I really want my pig to get used to me but its getting frustrating that it will not do anything. PS I bought it from a petsmart (only one in the cage).
