My fiancee and I have two:
Frankie is 7, and was my fiancee's cat for a few years before we met. Frankie was historically very standoffish, and was very selective in who she would hang out with. Luckily for me, she decided that she liked me a lot, Frankie crawled into my lap the first time I met her.
Frankie was always very reserved and shy; one reason being that we found out 6 months ago that she was in fact quite sick. Having never been spayed, Frankie developed an extremely infected uterus, and was, in hindsight we came close to losing her. At 7 years old, she weighed 7 pounds. After surgery, she was 6 pounds and incredibly weak.
Months later, she is around 12 pounds, and extremely happy and healthy.
Our other cat, Sippy, is about 15 months old. On our first date, my now fiancee and I were walking back to our cars when this little wiry kitten came trotting towards us from underneath a bridge, meowing her little heart out. We stopped and pet her, and then continued our walk. This little kitten followed us, almost always underfoot and meowing, for 2 miles. My fiancee took her home with the intention of taking her to a shelter the next morning, but the little one was just too persistent and ended up staying.
Sippy is a crazy little kitten. She likes to play a lot, and uses her teeth and claws without discretion. When she is in a calmer mood, though, she is the sweetest little kitten you will ever meet.
