You put your hand under it's but and lay your other hand on it's back. The guinea pig should be leaning on you.
you should never put a guinea pig with a chinchilla
not necessarily; if you leave one guinea pig in the cage with the sick guinea pig, the guinea pig that is not sick can get sick; you should separate them just to be safe but if the guinea pigs start to get lonely, put them back together
No, guinea pigs should not be put in a guinea pig ball because they have delicate spines that can be injured by the rolling motion. It is better to provide a safe and spacious enclosure for your guinea pig to explore and play in.
put him back in his cage.
it means that YOUR guinea PIG LOVES YOU
it really depends on the guinea pig, some get along fine with friends some don't
Put him back down!
You should just put it in a cage.
Do you mean a harness? If so, it shouldn't be put on in the first place... You should let your guinea pig have supervised floor/lap time :)
As they get in they run back into a hiding place.
Pick it up and put it on it's feet?
