their genes
Gerbils are actually the cross between a mouse and a rat.
no
some hamsters are bigger then gerbils e.g. syrian hamsters.
Gerbils are animals that look somewhat like a mouse, but bigger. They have a good sense of smell and hearing, but poor eyesight.
it depends on the type of gerbil
Things that are bigger than it.
Maybe. It mainly depends on the gerbils and dogs themselves. Some dogs like small animals and really want to play with them, some don't. Most gerbils get really timid around bigger animals, but not all.
One reason is gerbils have furry tails unlike mice having naked tails. Mice are a little smaller than gerbils. Third gerbils are much more active then mice. And finally mice normaly have much bigger ears than gerbils. I hope this helps.
It makes a warning noise to alert other gerbils in the colony that 'something' might not be right. It puts the other gerbils on alert too, to be aware of potential danger.
No it makes your butt bigger :D
it makes it bigger because your fat
No, because the average length of a guinea pig is 8-11 inches and width of 3-5 inches, and a gerbil is way smaller, with a length of 3-4 inches and a width of 2-3 inches. And guinea pigs are more timid and affectionate. But if you like scaly tails and bites, you could probably own a gerbil.
