Not completely unconditional. Gotta feed em when they're hungry or else they're pains in the ass.
My cat would wake me up in the morning meowing his head off 2-3 hours before my alarm was set to go off. I'd reach down by the futon and throw one of my shoes in his direction (not to hit him, but just to scare him off)-- that fucker can wait until I wake up.
Lately he's been better about it and only wakes me up maybe an hour or 30 min before my alarm is set to wake me up, so now I just wake up, feed him, and go back to bed until my alarm goes off.
But now he's fucking with me I think. After I've fed him and go back to bed, and he's done eating he starts meowing again, and I partly raise out of my bed and say "Now what the fuck do you want?"--not in a loud, angry way but more a groggy annoyed way-- then he immediately runs upstairs. It's like he's thinking "Yeah, throw shoes at me motherfucker? Now I'm gonna wake you up even when I don't need to be fed. Take that, fucker!"
He's cool as shit, though.
And that is why I love cats
They think, other animals just do. One of mine can open doors, and if you try to have a lazy morning he will open the bedroom door and yowl at you until you get up and feed him, sheer genius.
And yes, you gotta feed them, but that's it really, for that they will try to kill you on the stairs by wining round your ankles, sit on your neck on a hot summers day like a scarf, lie across your keyboard when you HAVE to get that email sent off, and take off round the house for a mad half hour every evening.
Whereas my kids, you feed 'em, do their laundry, act like a taxi service, nurse, maid, teacher etc, and they fight, argue, make mess, and give you grief. If only I'd had the animals before the kids
