They can but probable not. Unless they grow up from birth then you can give it a try . But in general most Likely not.
no
No its not, i guinea pigs cage is way bigger. & you should not have the same size of guinea pig cage as your hampster.
you shoudl not put a hamster and a guinea pig in the same cage no matter what.
if they like it let them but don't be surprised when they have a baby mixed who knows it might be a cute baby.
Erm, I wouldn't recommend it...
No, that would be cruel. A CAGE at least the width and length of a 20 gallon fishtank in comparison. At LEAST. Would be better suited to a guinea pig.
in its cage i say. i have a hamster and i have to go to school, i feed him in the morning and i leave him in his cage, when i come back i put him into his exercise ball , and then i feed him again.
because guinea pigs are aggressive
Yes, you can use a fish tank as hamster cage and it works really well ~ better than some of the wire cages because there is no chance of the hamster's feet getting caught in the wire. The tanks are easy to clean and provide a lot of room for a wheel and toys for your hamsters. Just make sure to get the wire lids that are made for the tank and tank clips if your wheel or toys are very tall.
With separate sides and protection
No not in the same cage cuz like bigger people bully smaller people, the guinea pigs will hurt the hamsters
Syrian Hamsters will kill and eat a gerbil, do not put them together in the same cage.
