Hi. I've just noticed that one of my guinea pig's eyes looks slightly smaller than the other. Is it possible that some gps are born with 1 normal eye and one slightly smaller? Or could it possibly be an injury? While i was watching him, i saw that he would close his eye a little, then after like 30 seconds he would open it, repeating this over and over again, as if he was falling asleep. While he has his eye slightly closed, he blinks, but only with that eye, as if he's winking. It doesn't look red or swollen. He's not scratching at it.. However, sometimes when he tries to sniff Kasper's [2nd gp] chin, Kasper sort of rams his nose into Flyn's [gp with weird eye] eye, maybe nipping him, i don't know. Is there anything i can do, or should i worry about it? I tried to take a pic, but he won't stay still.
