Well I sure am glad to see this post. Because my kitten never ever has covered his stuff.
And i had always wondered about that. But now I see alot of people that thier cat does not cover it up either. Well that's good. I now know that my kitten is not the only sicko in the bunch.
It's not really a big problem for me though. I scoop every day, and we use the litter that gets the smell out right away. That really does work. It's like "gets oders on contact" or something. At least that's what the phrase resembles on the container. But it works.
We have two litter boxes, and that never helped with the not covering the poop problem.
Now, if i could only get him to poop in the litter box more often than not......
