Junior Guinea Pig
Sadly I don’t know the age of one of them. My other two have had URIS about once or twice. My oldest cinnamon hasn’t had any URIS so far. So I think he’d be the safest bet.It's worth researching all options thoroughly including talking to local vets about their experiences with guinea pigs and how often they see them etc. Very experienced vets can get almost 100% success rate. Age and overall health of the piggy in question is vital to the outcome too
