It is very normal for your guinea pig to scratch themselves on occasion, but if you feel that they are scratching repeatedly and more than usual, then this could indicate skin parasites. Hair loss and white dust in their fur are two other indicators that they have an infestation. There are a number of different parasites that can live on a guinea pig and will be passed from one pet to another. If you treat one guinea pig, then you will need to treat them all in order to eliminate the risk of further infestation. Because eggs are likely to remain in the cage, a full clean and disinfection will also be required. Not only are parasites a nuisance but they can be really irritating to your pet, which is why they're scratching so much. Our range of topical treatments for common parasites will help to eliminate any unwanted visitors in your pet's fur quickly.
