Hi. I posted a thread on here just over a week ago asking for advice about my Guinea pigs fighting. Well long story short I have had to split their cage so they aren’t together anymore, but they are still happy to snuggle together on my lap and play outside the cage together. Now, the other night one of my piggies, Nutella, started chewing on his bars. I thought it was because I had ran out of the good hay and had to give him some cheap stuff until the good hay arrived and he wasn’t happy about it, but they hay arrived yesterday and he’s had a full hay rack but he’s still chewing bars, so then I checked his teeth to see if there was anything wrong there but from what I can see his teeth are perfectly healthy, unless it’s the ones at the very back that I can’t quite see. He also always has things to chew on so I’m not sure it’s that. So now I’m wondering if he’s missing his piggy brother Cashew? Any advice?
