Gerbils are known to be sweet, curious, feisty, and clever. They are one of the smartest mammals, if you work hard you can teach them tricks. They are not prone to biting their owner as long as they are handled properly and regularly. Gerbils are wonderfully social animals and actually have to live in pairs for life or they are prone to dying from depression. http://www.egerbil.com is a great site for the behavior of gerbils.
Gerbils really don't care about the color of the other gerbils in the tank with them, they really care about personality. For all we know, they could be color blind.
No, not only to gerbils come in several different color varieties, but as with any animal each individual has its own personality, though with gerbils it doesn't vary as much as with say dogs.
No, not usually.
pet stores, usually
$13 or 15
If your rabbit is very tame, it's about the same but usually rabbits aren't as tame as gerbils So, most of the time a gerbil is more playful with humans and other gerbils.
Sometimes they can be really fat. They are usually skinny, not too skinny.
5-7 years my good friend
Usually cats, dogs, hamsters, gerbils, or fish.
I would take it to a vet right away. When gerbils don't eat it's usually a bad sign.
You usually feed gerbils muesli or nuggets from the pet shop or WAG food which is much cheaper but is not as good for your pets they also like bread and fruit .
well it depends, wild gerbils usually live in warm, humid, climates such as the desert. but if their not they live in a cage. ;)
