The Peter Gurney Guinea Pig Pages - Itching Itching.
Guinea pigs can suffer very acutely from itchy skin.
This is mainly caused by either fungal or parasitic skin infestation, Scabs caused whenever the skin is broken can also be troublesome. If you can get in early before any lesions have been opened up by scratching, then Eurax ointment is excellent. This is formulated for use on humans but is perfectly safe to use on guinea pigs. More often than not the damage has already been done and the only course open is to use the 'baby bootie' technique or 'full body stocking,' in the shape of Tubigrip bandage. I have never been successful with the back feet binding technique, which is done by using an initial layer toilet tissue and then binding over with Micropore tape and ends up by looking like a pair of baby's booties.
