I am posting this on behalf of my sister in law because she doesnt know what to do and i am not g.pig expert. She has 4 girl g.pigs, 2 are quite new, had them about a month now and have been getting on fine. Roise is quite old and the vet has said she hasnt got long left. My sister in law thought she was dying yesturday so she brought her inside. When she put her back one of the new guinea pigs attacked her. My sister in law doesnt know what to do now? Advice please. Thanks.
