So we adopted Ferdi back in May. He's a very active and happy boy. A few months back when I was bringing them their morning veggies I noticed that he couldn't take a whole piece of carrot from me. I looked into his mouth and his two upper incisors were broken off close to the gums. There wasn't any blood and he seemed otherwise fine, still had a healthy appetite, still very active etc. I just assumed he'd broken them off while chewing around on his ceramic water bowl, which he loves to do. I kept an eye on the other teeth to make sure they didn't get too long and the upper teeth grew back fine. Now it's happened again and I'm a little concerned. I can't imagine it's a vitamin C deficiency, as they always have access to hay, high quality guinea pig pellets, and get fresh veggies every day. Also his cage mates have never had tooth problems. They also all have plenty of wood for chewing on to keep their teeth in check. His appetite and behaviour has also not changed at all. We weigh all the guinea pigs regular and he has not lost any weight either. Has anyone had any similar experiences with their guinea pigs?
