Yes, you may take them both in. If they love each other i would recommend bringing them in together so they can get a sign the says "we love each other and we have to go home together!" There is a surrendering fee of $30. I would recommend also making an appointment to surrender them because they may be able to help with your issue.
Sad that you must surrender them but if you must this is probably the best place to do it. One of the cats I adopted there was a surrender and we are so happy to have her in our life and home. They will help to find a good home. You can probably get an inexpensive cardboard carrier or borrow one and take them together. It would be best for them. Good luck to you.
