We got the cats in their cages , and brought them into the rental office of the complex where we needed to sign the lease and get our keys ( they were a huge hit - everyone cooed at them ) . We drove over to our apartment from there , and one of my major worries was assuaged immediately . See , we had rented our apartment based on a model , without ever having seen the actual living space .
Question: What may be the reason for them bringing their cats into the office ?
The answer to the above question:


They did n't have keys for the apartment yet .
