I have 2 cats, Baby and Milo. Baby is about 13 years old, and has had a problem urinating and defecating other than the litter box. We have tried using different litter, buying a new box, changing the litter every day. Even moving them do a more discreet location. She continues to do it. She caused us to lose our $600 deposit from our apartment. Now she is doing it in our new house. I have brought her to a few different vets, and they all say there is nothing health-wise that is wrong with her. She did this BEFORE we got our other cat, so it can't be him. If it was, it would be too hard to give him up. He is attached to us, and is afraid of other people. Short of putting Baby to sleep, is there any other alternative, or any suggestions? My hubby wants to just bring her to the shelter. I have had this cat ever since she was a kitten from a litter that my dad's cat had. She has been my constant companion through a whirlwind of life changes. She was there for me for every tear that I cried after my grandma who helped raise me, died from leukemia. She even kept my grandma company during the day when I would be at school. But the peeing and pooping outside the box is making my hubby angry, and me very depressed. I would rather put her to sleep rather than bring her to a shelter where I would not know what would happen to her. Besides, she's 13...too old for a shelter. Please help me. I need guidance.
