Some cats don’t want the cover, I guess they instinctively want to be able to see all around them in case a predator is sneaking up on them? I hope it’s somewhere out of the way, where you don’t have to watch the cat doing it’s business each time. Maybe a short screen around the box, enough to block your veiw, but not a cover would work if that is so?
One thing you might try to get her to use the cover: Get a cardboard box on its side or with one side cut out big enough to hold the litterbox and the cat. Place the box near the litterbox, and get the cat used to going near it. Slowly move the litterbox inside the box over a few weeks, until the cat is going inside the box. Replace the box with the cover.
Thanks everyone for your continued help.
I’m not sure what kind of box the owner of the mother cat used. I didn’t really see it. But the cake pan didn’t seem to scare them, they used it, it was just those few times that her kitten “forgot herself”.
My kitten and my sister’s kitten are from the same litter, so I don’t think it was that they didn’t want to share. My sister says her kitten seems to also be accident prone.
A funny side note, I decided I’d had enough of the mess made by the cake pan, it has such low sides and all that every time the kittens went to use it (my sister’s is home with her now of course) they’d make this huge mess of litter all over. I had bought a nice covered box, but was concerned that it would scare her too much to try and get in and out of it.
But finally, I was just tired of dustbusting litter 8 times a day (oh, and I don’t like the mess either, so my kitten is very spoiled, I clean the box every time I go in there, the longest she has to wait for a clean box is when she goes during the day and has to wait til I get home from work). So anyway, I put fresh litter in the “big kitties’ box” and put the cake pan with litter inside of it. Cleaned up really well around the whole kitty box area, and then went and got an old phone book to make a “step” so she wouldn’t have any trouble, or be afraid to get in an out.
Then, I went and got her and put her in. She explored, played in the litter, went potty, and then just HOPPED out. The next time she went back in, she just ignored the nice phone book step and hooked her claws over the edge and climbed in.
Sheesh, wish I’d have done that a week ago! At least she’s using one new kitty thing. I got 60 or 70 bucks worth of kitten toys and accessories, including a small “cat condo” with specially treated catnip carpeting and its own little hideaway.
Does she play in it? She does not. Does she play with the other fresh new kitten toys? Only rarely. Her favorite toy? A damned platic grocery bag. Or better yet, using my legs as her own personal climbing trees. Or torturing the poor dog and stealing her toys.
Someone mentioned making sure she had a place to get away from the dog. ha 
The poor dog needs a place to hide from her. This is a lot of fun though, I’m really glad I got her.
Pictures soon!
Welcome to cat ownership.
When we got our kittens, we had a “kitten shower,” with a spending cap of $0. People brought whatever junk they had around the house that a kitten would have fun with - they got a paper bag with a hole in the bottom, plastic drinking straws, a foil ball, and some leftover pompoms from a craft project. All were well-used. (The point of the party was more to get them used to lots of humans, which worked pretty well.) But the expensive cat toys were mostly ignored - with one very important exception. I highly recommend this toy - it works even better than most other wand toys. Something about those spinning feathers really drives the cats nuts.
Of the various purchased or home made toys my rotten furbabies have littering the floor for me to trip over, one of their favorites is the ring from the top of the milk jug.
And like kids, they would rather play with the box than the toy.
Give this time, as cats don’t start responding to catnip until they’re sexually mature. She may come to love it.
