Cat House on the corner of Ass and Ass

No, you perves, not that kind of cat house! Although the corner of Ass and Ass is accurate enough (sigh). Anyway, as my mom's house is rather at maximum capacity for cats, as my house is sitting there empty, and as there's a bit of a feral kitten population in my neighborhood... well, you can guess where this is going. My house is now home to one cat (a very friendly cat, whom my mom named Cita - short for mamacita - only to later learn that she was not a mother cat at all) and three nameless feral kittens. Luckily, they've all figured the litter box system out! One of the three kittens is less skittish than the other two, who pretty much stay out of range of my mom. She's going over there every day and spending time with them in order to get them socialized. She's taken some pictures, which have been posted here. Let me know if you have any name suggestions for the kittens (two black and white, one grey).

UPDATE: Of course, the day I post this, my mom would come up with names for the little ones on her own! For those of you interested, here's what my mom has to say:

I named the 2 B&Ws Chico and Loca (for the shy one). (Or Chica and Loco, if I'm wrong about their gender. The little grey one is Shady. Anyway, Chico allowed me to pet him this morning (altho he's not at all interested), and even the other 2 were out more in my presence. Cita is letting Chico nurse from her. He can't be getting anything, and it can't be good for her incision [she was just spayed]; but they both seem to be enjoying it.
