It really depends on which store you go to, and then where the store is. The price of any animal would vary from store to store and place to place. You should look online at your local pet store to see how their price compares to other's around you.
well that depends on what you buy and how much it costs.
Not much In human portions not alot. But a gerbil will drink as much as it can.
Buy a cat...
A gerbil will cost about 10-20 dollars.
the fatter the gerbil, the thicker the bedding.
a gerbil is cheaper as its much smaller and cleaner
Treeton Pet Store for $3,000.
Average adult gerbil weighs about 2.5 oz
A hamster because they are cute
dont give your gerbil a 'water' bath use chinchilla dust
The average Gerbil can peak at around 15mph! Overweight or obese gerbils can't be arsed.
I suppose you could buy your dog a costume and pretend it was a very large gerbil...The two aren't necessarily mutually exclusive. The gerbil won't be running around free, it will be in its cage, and the dog won't be able to get at it.
