They're about 2.5 months old and look quite big for being babies lol. I was thinking maybe what I could do was zap strap some chicken wire along the outside until they're too big to fit through the bars.
I was thinking about that too threezero. I could get a small-ish hamster one for less than $10 at Value Village and just keep them on my shoulder or in a play pen when I'm home.
My other option would be to make a cage, sort of like this one:
