My friend is traveling this summer and asked that I care for her cat. She moved the cat in yesterday while I was out of town, and when I came back today the cat seemed to have claimed the bed as her own. 

She's friendly enough but if I get on the bed sometimes I get hissed at until I get off. Ive never owned a cat before so I'm not quite sure what to do. My friend is traveling all summer and I live in an efficiency, so kitty and I are stuck together now. I'm uncomfortable in my apartment, which sucks. I'd like to make this work
<bot>: caring for a friends cat who I think is being territorial. I don't know what to do because I've never owned a cat before.
