How much water your guinea pigs need depends on their level of physical activity, their size, and whether or not they’re pregnant. It also depends on how hot the weather is. As long as you keep their water bottle full and clean, your pets will have enough to drink.
Water bottles are supplied with the Eglu Go Guinea Pig Hutch
In hot weather, shade is as important as water – whether your guinea pigs are outside or inside they’ll need a cool, shaded place not above 75 degrees farenheit. For this reason, we strongly advise against keeping guinea pigs in conservatories because these are areas that tend to get very hot very quickly.
