I tried for weeks to teach her to use the litter box.
Did she learn what to do with the litter box or not?
No, and I've given up on teaching her.
Don't get discouraged, these things can take longer than you first expect. Just keep teaching her patiently and she will get it eventually.
Lol, she had bad aim when she peed. Its not my fault she couldn't learn how to use the litter box.
I think that you just got too impatient. It is going to take some time to teach them how to use the litterbox. Keep trying, they will get it eventually.
