My cat won't stop peeing on the bed no matter what I do and I can't figure out why. My cat never peed on the bed before a month ago when I tried to change to wood pellet litter. I took it out since she didn't like it and she stopped for two weeks but then she started peeing on the bed again. I took her to the vet and they said that she was fine and i've tried using Feliway, but it didn't work. I tried cleaning the litter box more often and added a third box. I've cleaned all the blankets, sheets, and the mattress she peed on with an enzyme cleaner but she just keeps peeing on the bed!! She doesn't always avoid the litter box, i've seen her use it but she pees on the bed every few days and it's driving me crazy. I feel like i've done everything i can but I can't figure out why she keeps peeing on the bed. I haven't tried to change my litter box setup much since she started peeing. I'm completely at my wits end with this problem.
