Cavy Kung-Fu
Adult Guinea Pig
It is a typical pattern for sorting out a disputed ranking that both piggies feel they can hold and neither is willing to step down yet. Dominance sort outs are not constant, they happen in rounds of face-offs, and they travel down the hierarchy. A newbie is tried from the top down until they find their rung - but that rung can be sometimes disputed. As long the dispute is not too up there, there is hope.
But if you are worried, then take him out and restart again. As acceptance and most of the major dominance has happened, the piggies will pick up where they left off after a quick reaffirmation of the ranking so far. Any neutral ground is somewhat better as long as the hierarchy is not fully sorted.
Thank you for your help, well I'll pop him back and see how it goes for an hour or so and put him in his cage over night if needs be. This is draining!
Is there anything I can do to ease this along? I feel so helpless!
