My female guinea pig Carmie has been chewing on the bars of her 3x4 c&c cage like crazy! She just chew,chew, chews ALL THE TIME. She has wood chews that she doesn't touch. She only likes the bars.She doesn't have a friend, so I am thinking that is why she chews soo much. If this is wrong then let me know. It's the most annoying thing ever, so I really want it to stop. Let me know what you think!
