My cats love everything! They always want to try my food. I don't let them though. They eat their raw food and that's all because the other stuff is bad for them.
I don't think I could stand the smell week old urine and feces. I scoop mine just before I leave for work and after I get home and get settled in. So about 6:45 am and again at 6:30 ish PM.
I think of it this way... I wouldn't want to have to put my bare feet all over old poop and pee to...
Your cat should see the vet to make sure she isn't sick. Most elimination problems are because of health issues. I would feel tarrible if I hit my cat for something and then found out she did it because she was sick....
