I have to disagree with the idea of keeping a hamster instead of a guinea pig—at least from my experience, my syrians have been more interested in burrowing than getting attention, and none of my hamsters have ever been the snuggly type out of the five I’ve had (which is fine, and you really have to respect that— i just don’t think that’s what OP is looking for). That, and, especially with syrians, most times your schedules won’t line up—I’ve had syrians who were only up from 1-5am and I barely saw them unless I stayed up late, which was needed for my previous female as, if she didn’t get free-roam time, she’d chew the heck out of her cage (which was also a 2000sq in cage).
My dwarfs have been a lot more sociable with me as their waking hours are either dawn or dusk, but still, not something to cuddle with after a rough day. Cute, and they do help me get through stress, but not as much and something I’m able to hold and stroke for more than a few seconds.
Also keep in mind hamsters also have expensive vet bills! Because they are smaller and less researched, it can take several tries with medication to find something that works, which can be killer expensive when the “walk in the door” cost is $100.
