i've noticed my jinnywigs bob and jim have been teeth chattering abit recently. nothing bad, just abit of posturing. but yesterday they had a proper fight. i seperated them, but they've been together for years now and never had a problem before. i put them back together tonight and all jim has done is try and hump poor bob bob is the alpha normally. but he's an old man now. jim is alot younger, but has already been through the hormonal stage a couple of years ago, so i can't understand it 8... would having jim neutered make any difference, i've read that having guinea pigs 'plums' off doesn't alter behaviour or anything? is this true? what would you guys do? i'd hate to have to seperate them after such a long time together, especially when bob is such an old man now, i don't want him to be alone 8... any advise please? x
