I work at a cat shelter and we have one cat there since she was a kitten and she will not and has never used the litter box!!! We have tried that cat attract stuff that guarantees the cat will use the box and she still wont go. Im thinking she just doesnt want to share because we have multiple cats and litter boxes in each room. This is going to cause her not to get adopted and its a shame bacause she is such a sweetie! Does any one have any ideas? Im sick of cleaning up the floor! Also she has been to the vet and they see no medical reason.
