Well I'm thinking he might have some pooping problems or his butt is really itchy!
Guinea pigs have a grease gland at the end of the spine around where their tail is. If impacted it could be causing pain.
they constantly have an itch
The guinea pigs jump, because they are happy.
from thier butts this is true
The same reason we jump.
Guinea pigs pur when they are upset and want you to stop touching them.
jumpy .
It's mostly male guinea pigs that are likely to attack each other because males are more aggressive toward each other. Guinea pigs don't have to be related and they sill don't fight. I have many piggies and none of them fight. Other then that guinea pigs are really cute, friendly,and cuddy animals.
Only in boys that happens cause if you don't neuter them that is what gets the girl pregnant.
to put it bluntly, if they smell something that turns them on they will squeak, purr and wiggle their butts.
They tend to jump when they're happy. It's called "popcorning".
Yes. the highest jump made by a guinea pig was 15 cm.
Guinea pigs are sweet, friendly, and sociable animals that love attention. They are also quite happy animals if they receive the proper care. Happy guinea pigs usually squeak, run around, and/or ''popcorn,'' which is a term for hop, jump, or skip.
Guinea Pigs have hairy bottoms because God made them that way and because it would be very cold down there if they did not have the hair. That's why we wear pants so that won't happen with us. Take care and God Bless!
