Um, I'm fairly positive that hole you saw was his belly button, and yes it is very normal in fact all guinea pigs have them.
Well he looks like a normal guy. You cant see his belly because his shirt is on.
Because it somewhat resembles a button and it is on your belly.
A chinchilla kind of looks like it.
The belly is big because inside is the baby growing
Yes , all guinea pigs are different. They vary in personality , looks and in intelligence. No two guinea pigs are the same.
If it was a boy guinea pig - yes.
when she looks like she has a baby in her belly.
I try to clean my guinea pig's cage around once a week or when it looks dirty.
It just looks smaller because it's dropping and not sticking right out anymore. It's normal for the belly to change later in the pregnancy.
no blue belly lizards do not have teeth. they bite and they are not poisonous.
I have a inny and i have mine pierced. innys are cuter with belly button rings anyway.. it looks funny with a outie.
bottom, for sure!
