i dont think its overly hard to take care of hamsters. You only need to wash their cages throughly once a week. Washing for one cage THROUGHLY takes abt 45 minutes? lets say if u wash on sunday and plan to wash the following sunday, it will be a bit stinky on friday saturday.
if u have the money it should be okay for you...cuz u will need to buy some toys, a nice big cage(which cost!)bedding(which will also cost) food, and other stuff. And if u change their food/water every 2 days and play with them(oo its fun to watch them play XD) they wont get sick, so no vet!(veryvery costly) YEAH. and if theres a nice spot away from da window indoors hamsters should be nice for you!
but rmb its a commitment for abt 2 years...so if u can do it go buy one!
