Gerbils should not be sold at less than six weeks of age. Beware of anyone selling you one younger, as the gerbil will most likely not be easy to tame. A six-week-old gerbil pup can go for $3 up to $12, depending on who you go to. Large retail pet stores typically sell theirs for $10+, while breeders go for about $5-$10.
If you mean raising them, it isn't the gerbil pups that will be your expense, at least for three weeks. Momma gerbil, however, will be needing extra food and water, and the cage will need cleaned more often with 6+ gerbils running around in it. Gerbil pups will start eating food around 3 weeks of age, and then the food bowl will really need refilled! Major expenses will come around 6-8 weeks (whenever you decide to separate them) as you will need separate cages for female and male pups, and separate supplies such as water bottles and exercise wheels. However, raising lil gerbil pups is generally a sweet and rewarding experience, if you know what you are doing.
Normaly 3-4 pound
the fatter the gerbil, the thicker the bedding.
A gerbil will cost about 10-20 dollars.
From what I read you need to put at least an inch of bedding in there cage and give them toilet paper and cardboard tubes to chew up to make a nest.
about 10-25$
Yes
She might be allergic to the bedding. If you are using aspen bedding, this is probably it. Eco bedding will not make your gerbil have an allergic reaction. Still, I would consult with your vet to make sure.
They're cheap pets.
well that depends on what you buy and how much it costs.
Wool fibers and commercially sold "fluff" is generally a bad idea for gerbils, as it may get caught around a leg or the gerbil may be allergic. If you want bedding for your gerbil, throw in a wad of unscented toilet paper. They'll tear this apart and build with it. :]
It's about $5- $50
Chris Madden's bedding on average costs 200.00 for a complete set at places such as JC Penney. Deals on Chris Madden's bedding can be found on places such as Amazon or eBay for a much lower cost.
This is perfectly normal. They are trying to hide the gerbil from you and to keep them warm. Maybe leaving them alone would help.
