Hello everyone, i am new to this thread and would appreciate any insight anyone might have. I have 3 male guinea pigs that are 14 weeks old and have been doing great settling into their new home the last few weeks, however during one of my daily health checks i came across what appears to be a scab on one of my piggies lower belly, i dont remember seeing this scab before which is why i was concerned but it hasn't changed in the last few days. He is acting completely normal, playing with the other piggies, eating and drinking well and popcorning around, i just dont know what this could be? it is light brown, even smaller than a pencil eraser, and on his lower belly. When i touch near it he doesn't react like he is being caused any discomfort by it. i read somewhere that guinea pigs have belly buttons, but neither of my other piggies the same age have this, so i just thought i would see if anyone had any thoughts. thanks!
