Junior Guinea Pig
my very placid and happy 5 year old girl today has turned on her cage friends started teeth chattering for the first time ever chased and bitten the other girls on the back and I can't understand what's happening to her, she has attacked all of the other 4 any ideas after 5 years of peace and quiet, she's eating and drinking well just s shock to see this sudden change in behaviour.
That any sudden change in behaviour can be an indication of illness so would recommend a vet visit if it continues.
