Also called Soya milk, soymilk, soybean milk, fake milk, or soy juice, soy milk is a drink made from soy beans. It is a traditional drink in Asian cuisine and is produced by soaking dry soybeans and grinding them with water.
So can guinea pigs drink soy milk and if they can how much can they drink?
Unfortunately, guinea pigs cannot drink any kind of milk at all. Guinea pigs are strict herbivores and cannot have any kind of dairy product. They are just too bad for them and will hurt their tummies either making them sick or giving them diarrhoea.
So steer clear of giving them any kind of soy milk
