Hi Selina
Guinea pigs are normally very active little animals and scurry around a lot. So it's abnormal for your guinea pig to not move much. It sounds like the reason he is reluctant to move is that he has a problem with his back legs which is the cause. You really should get that checked out by a vet to see how bad the problem is and if there is any treatment that can be given to help him. Other than that there's little you can do to make him walk again. You are helping him though by taking his food and water to him and by making it easy for him to get access to it. Sadly if the problem has been present for a while and there is nerve damage to his back legs there may not be much treatment that can be offered but it is worth getting him checked by your vet.
