I'm puzzled as to why my cat will only defecate in the bath tub. She urinates in the litter box 100% of the time, but will only have bowel movements in the toilet. There are multiple litter boxes in our home, I've made sure they're in private locations, and I've tried a variety of litter. Each time she goes, I clean the spot with a spray-on bleach product, then follow up with a spot-eliminator product. It seems like no matter what I try, she insists on leaving "tootsie rolls" twice a day. Any suggestions?
