A reason it may show might be because they are very skinny or something is wrong with it. Maybe something happened to its back bone, if you dont hold its rear the back bone and or spine may break and if it was dislocated because of that it may show. if you have anymore questions just ask me because i have a guinea pig of my own and a very large manual and i would be glad to help you with other questions about your guinea pig!
The same reason we jump.
There is no reason other than that Guinea Pigs evolved to be mammals.
No, there is no reason to kill a guinea pig for scratching someone.
no, guinea pigs could hurt the gerbils by accident (big size difference!)
This depends on the personality of the guinea pig and the ferret, they could but they could not.
No, a guinea pig is not an invertebrate. The meaning of "invertabrate" is an animal that has NO backbone. Something like a leach or a tick is an example of an invertabrate.
They could be hungry or thirsty
The first people to keep guinea pigs as pets were sailor's. They brought them to Europe from south America. (Which was perhaps confused with Guinea, in Africa). These little animals were called guinea pigs because of the squeaking, pig-like noises they make.MJC
they sold for a guinea lol. they're native to south america.
Guinea pigs, like all animals, need exercise or their muscles will atrophe (go soft). This is the reason tanks for guinea pigs usually have a wheel that the little animals can run around in for exercise.
Yes a Guinea Pig is a mammal with a backbone, Making it a vertebrate.
No!!!!!!!They are actually part of the rodent family.
