Context: Two cats ( one is an itty bitty kitty that they bought a couple of days ago ) , two ferrets , two rats ( one hairless ) , and some fishes . Oh , and an iguana who likes to watch TV . It 's been basically like it is at home ; lots of sitting around being hungry and sleeping on either the couch or the floor ( Rico and I trade off ) . There are , including me , six people living here at the moment , in a two bedroom apartment .

3. It is the only way we can keep from sleeping on the floor .
Answer: 1
