maybe she doesnt like the litter in that box. she could also be mad at you all or have a UTI (urinary tract infection) cats can get that its very sad. and you Lexi is beautiful.. me and my bf want to get a Himalyan (spelling?) someday. they are very pretty too. I thought it was great, I got my kitten Zoey back IN may and she was 7 weeks old. and me and my BF went and got alota stuff for her and the litter box and she used it right away! I was so happy that she new how to use it and we didnt have to teach her.. also, there are these cats treats they are "temptations" ALL our cats go CRAZY over them! they are only like 1.28 at walmart for a regular sized bag but maybe that will also help her.. some advice LOCK THEM UP! haha my cat Zoey will tear them open and eat the whole entire bag. she has done that a few times and she got really fat.. so now I put them in my dresser lol where she can NOT get into them and give her maybe 1 or 2 a day.. also when u shake them allll the cats go crazy and come running for them lol I love cats
