The Kitty Blocker!!!

Ch
Okaaay, so my boyfriend and I have lived together for 4 years now and I am so sick of his cat. This bitch ass cat is 17 and my boyfriend is 26. So this thing has been around most of his life and is now tormenting mine. She pisses and shits in my closet, meows allllllllll throughout the night, kneeds on all my nice furniture, and gets my bed all furry. Also like a week ago I was giving my bf a blowie when I had to stop because there was a cat hair in my mouth!?&@$ UUK! My question is... how long do cats live?  And the 2nd.. does anyone want to adopt a ole bitchy ass cat?.. any takers??
