Not all guinea pigs hide in their houses/huts. They only stay in their all the time because they are scared. The first couple days you have have your guinea pig they will always hide. The more you hold your guinea pig the closer it gets to you and when the are in their cage they will come out and not be scared.
You can't take Guinea Pig's for a walk with leads or anything like that as they are very bad for a Guinea Pig's spine. You are best to either let them go in a run outside or let them out in your house. You are best letting it run in your house, but keep it away from wires and spaces it can hide in. You shouldn't use a guinea pig harness or lead as they can damage their sensitive spines.
Hide.
Somewhere the guinea pig can sort of hide. Try to use a piece of curved wood bought at pet stores for them.
yes only if the doll house is big enough
no
A guinea pig only has one heart.
Only the guinea pig she mated with but be sure to separate them after birth
If you only have one guinea pig get him/her another guinea pig friend of the same gender. It could be lonely.
By bad guinea pig do you mean it bites? A guinea pig will only bite if it feels threatened, scared or hurt.
No, only girls get pregnant :)
A hutch
Omg yes cause they are cute and cuddly and a 8 year old could take care of it. If you really want to get into it you can breed your guinea pig and little babies will come out they are soooooooo cute!!!!!!!
