Thanks for using Petco Pet Education Center, formerly Petcoach! This may actually work fine. I would encourage you to introduce them slowly and supervise them at all times at least for the first week to make sure they are getting along. I recommend you consider using a product called Feliway which may help tremendously in calming them in stressful situations like this could be. You may find that online or at your local pet store. Good luck and have a great day!
