Give your new friend places to climb so she/he can see out windows and over top of things. They will climb on your kitchen counters and sewing machine otherwise! Yours is still young enough to be rather energetic and playful.
Cats also love boxes. Just saw one turned upside down, one end cut off, an old t-shirt stretched over the whole box with the neck hole for a 'door' into the box. Great idea!
Long twigs with a feather or two tied to the end also makes a great plaything for you to hold and dangle before her/him.
You are more blessed than your realize, cats are very entertaining!! I miss mine at the farm immensely.
