No there is not special water for guinea pigs. Although there are vitamin drops you can put in the water. I currently have a guinea pig and I give her tap water with nothing added.
yes you can give a guinea pig a bath with just water but they will not be as clean as when you give them a bath with shampoo and yes they do make special shampoo for guinea pigs don't use normal soap on guinea pigs you can find this special soap at petsmart in the guinea pig area
Any guinea pig shampoo should be fine for your guinea pig but you might want to ask your vet, an employee at a pet store, or friends with guinea pigs.
Tap. But they have to have fresh everyday
some guinea pigs love the water, others don't. Its all down to the preference of the individual
do not bath your guinea pigs ever! only bath them with special washing shampoo from wilkinsons, even if you get that its only if your guinea pigs are really dirty. It will have writing on the back to read or get special shampoo from ebay or a pets shop.
yes
Guinea pigs needs to have fresh, room temperature water available at all times.
Guinea pigs can swim but only in shallow water, NEVER let them out of your sight and don't put them in with salt or chlorinated water
because the water and the drainage water will not go inside the nose of the pigs
no
2 water bottles..
Because either the Guinea pigs want food, water, or just simply want to be played with.
