Supreme Science Selective Guinea Pig
£7.49
If you are feeding Selective to your guinea pigs for the first time, make sure you change from one food to another, gradually over 10-14 days. At first, you should mix a small amount of Selective with your guinea pig’s current food, slowly decreasing the old diet, whilst gradually increasing the quantity of Selective. A sudden change in diet can cause digestive upsets – even when you are changing to a better quality diet
