Rubester
New Born Pup
Until a couple of months ago I owned two sisters who died at the good old age of 7. Especially when they were younger though they used to fight lots, trying to nip each other now and again. If you are having this problem then I can tell you that there shouldn't be anything for you to worry about and if you think about, how many brothers and sisters do you know that don't fight once in a while? As they got older it began to stop and they were practically inseperable most of the time, and when the first one died, the second died of a broken heart at the loss of her dearest sister. So if your brother or sister guinea pigs are fighting just try to keep them apart to calm down for a bit and they'll get over it, they love each other really.
