Can Hamsters And Guinea Pigs Be In The Same Cage?

You should never house your Hamsters in the same cage as your guinea pigs. Both of them have severe differences when it comes to their personality and lifestyle.

As guinea pigs need to be kept in pairs, they need a relatively larger cage size. A pair of guinea pigs need at least 8 square feet of space. A larger cage in turn applies more expenses and frequent cleaning.

On the other hand, Hamsters can live in a comparatively smaller cage. They can stay comfortably in a 30-40 gallon tank or say 4 square feet of space and 20 inches height square feet of space.

Another thing to keep in mind is that Hamsters love to burrow. Burrowing is in their natural instincts. Therefore, they must be provided with a lot of bedding material in their cage.

A guinea pig, on the other hand, does not need any burrowing material in its cage. They just need lots of hay to chew throughout the day.

Also, the guinea pig cage needs to be spot cleaned every other day and the bedding must be changed every week so that debris from hay doesn’t build up. A Hamster’s cage, on the other hand, does not require much cleaning. You can easily get away by spot cleaning their cage once a week and deep cleaning their cage every 30-40 days.

Hamsters are omnivores, which means their food and energy requirements come from both, animal and plant matter.
