They are low maintenance as they are not gluttons like dogs and can be left with a supply of water and food and clean litter for a couple days at a time.
They won't run your life like dogs will.
BWAHAHAHAHAHAHHAHA. Maybe "lesser maintenance" unless the cat gets urinary issue going, or an irritable tummy that only manifests itself as projectile vomiting in the middle of the night. As far a gluttony goes, I've never seen a dog eat all ITS food in a big darn hurry, yack it back up on the carpet, go eat all of the other dogs food like a starvation victum, yack THAT up, then whine for more.
Kewl Beans about rescuing the kitten garyk/nm. Post up some pics so we all can share. My first cat Bastet (still around 14 years later) was also a rescure kitten. Some {CENSORED} {CENSORED} had tossed her in a garbage dumpster to get rid of her. There is a special place in the Christian Hell for the villain who did that, which will be a far cray from what *I'D* if I knew who the creature was.
Grampter: I think this (http://www.sweetscoop.com/) is what you may be thinking of. I use it in two of the four cat boxes in my home since two of the four cats prefer it to the clay based clumping litter. Clumps decently enough to easily scoop out of the boxes, although its lighter per unit volume than other litters, so it does not "feel right" to the two cats who don't like it.
