Many Singapore guinea pig and hamster owners love their pets as family members in 2013 as compared to 20 years ago.. They would seek veterinary treatment early.
This "Be Kind To Pets" Veterinary Educational Video shows how I drain a ruptured leg abscess in a young guinea pig in Singapore. Sedation would have been given if the abscess had not ruptured so as to reduce stress and discomfort in the young guinea pig. However, there is always the anaesthetic risk of death due to sedation. In this case, sedation was considered unnecessary as the drainage of the pus would take only a few seconds by me.
