Here is a thread about it.
My inlaws owned a pet store for many years that I managed.
They raised their own hamsters, gerbils and guinea pigs.
I liked the guineas alot. So cute, and much friendlier than the hamsters or gerbils.
They can last 5-7 years with proper care, that is a good thing or a bad thing for some people.
Cages must be cleaned, they don't stink if cleaned, trust me I know LOL. I would dump cages weekly , but daily I would scoop it a bit just like a cat box , if I saw a big mess and add fresh bedding, took no time. I used aspen bedding and care fresh.
They must have vitamin C.. I liked to give it in oragnes and carrots, but you can give it in tablets and drops in teh water. Fed our guys a scoop of food a day in their bowl and a few pieces of carrots or carrots, sometimes timothy hay.
If you get a female and then later on decide to get another, make sure you buy another female. Past the age of about 9 months if a female has not given birth her hip bones will fuse shut and if she gets pregnant she will have to have surgery or trying to give birth will kill her.
They are happy to see their owners and will make lots of noise when they see you .
I am looking forward to getting my son one , but with two cats in the house we will wait a few more years.
