We have 6.
2 started out as mine - Pukis (pookie) and Esmeralda.
Pookie is about 13 and is a grey tabbie found on the street in the lower east side at about 5weeks. She's getting older but still has running fits and loves catnip and keeping everyone in line. Esme is a calico from Barc shelter in Brooklyn - she's about 6 now i think and loves to head butt you when you don't expect it. She never meows. ever.
3 came with the butch

Zoey - orange and white, not sure the age - street kitty now lovey dovey thing. Molly - sweetest cat ever - very gentle - about 4 yrs old - grey tabbie, Shane - she's a butch kitty. Tortoiseshell and bossy.
youngest is Morgan -a black kitty about a year old now. Found taped up in box in the street/trash. people are assholes. She's the coolest kitten ever. She loves squishy balls and hair ties and will fetch them repeatedly for you to throw. and throw. and throw. She also drops them on your head while you are sleeping. Recently she's decided 4Am is a good time to wake up at which point she climbs on me nuzzles my neck, purring loudly, and starts licking my nose, eyelids, chin...
they pee and poop a lot. i believe my main role in life is litter scooper.
