We've only had our little piggies for a week. Initially they were in a ferplast 100 cage (which was far too small - we quickly realised) and on Saturday we moved them to a c&c cage (2x4).
One of the gps (Sherbet) has always rumbled, walking slowly and wiggling his hips. The other gp (Jeff) has started to chase Sherbet around the cage and it looks like he's being a bit of a bully! There's no teeth chattering (that I have heard) but Jeff did catch a mouthful of the Sherbet's fur earlier. Both are delightful when out and being held / cuddled by me and DC, although Jeff is more inquisitive and will nudge our hands more. Both will come to eat from our hands with a bit of patience and perseverance.
Is this going to cause problems or are they still trying to figure out the boss pig? At other times they are happy munching hay together and will snuggle in one hidey (even though there are two). Just want to get it right for them.
Sounds fairly normal. Don't be tempted to separate them unless it escalates to full on fighting with blood. They will sort it out. Just make sure there's two hidey holes so they can get away from each other.
My Scruffypig and his original friend, Smooth, bickered constantly and I always put their igloos with the doors facing away from each other so they didn't have to look at each other. They did pine if I took one out of the cage though. Only had one instance of full on fighting and they really went for it, rolling on the floor trying to bite each other. I threw a towel over them to confuse them (never use your hands to separate warring pigs) and then separated them by putting mesh across their cage. After a day, they broke through my carefully crafted barrier and were back to their normal bickering ways, but never fought again.
Scruffypigs current companion, Gingerpig, adores his uncle Scruffy and tries to lie next to him all the time. Sometimes Scruffy has to chase him away so he can have 5 minutes peace. (If they had an ensuite, he'd probably lock himself in there with a book).
Food is a great distraction if you notice them getting a bit too nippy. Just throw in a bit of cucumber or something and they soon forget about arguing.
They should work it out themselves, you may find they start to jump each other but that's just to establish who's boss that's nothing to worry about! If they draw blood then separate but it sounds like their hormones are just starting to kick in! You can buy calming sprays but I wouldn't worry about it too much at the moment
