How to add two variable in bash?

I have two female chinchillas, is it possible to add two more females to the cage?

• I already have two female chinchillas (8 and 9 months) and I work at a pet store, the other day the manager came to me and explained that if the 2 chinchillas in the store (roughly 6 months) didn't sell within the next month (they've already been at the store for 5 months), they would have to be adopted out, she asked if I would be able to take them. When an animal has to be adopted out, the store prefers to have them go to employees or their families. If I take my two girls to meet the other two in a neutral space, what is the likelihood that they would get along in a HUGE cage? I have a Lg Clean Living Cage, and I would end up getting 2 more add-a-levels for the two new additions. Unfortunately I don't have space in my apartment for a second cage, just 1 larger one.

• Answer:

  You can, but they might not get along. I would try it, if i were you. But if things start up, get another You could get a shelf, and seperate them (:
