I wanted to start by saying sharks don't have fur and those are not house plants, but since you are new here you may not get my sense of humor.
I like your bookshelves! Have you just moved into a new place? (Sheesh, am I nosey, or what.

Looks like it could be Monterey Cypress; possibly 'Goldcrest'.
I found an article in Country Living Magazine suggesting that the Cupressus macrocarpa/Monterey Cypress sold as mini-indoor Christmas trees can be a good houseplant.http://www.countryliving.com/gardening/garden-ideas/advice/g1341/indoor-gardening/?slide=7
To paraphrase that line in the movie 'Jaws'....you're gonna need a bigger house.
