We have spent over $1200 on my parents house tabby. Finally they found crystals in his urine and he’s been on medication for a month now. But he still pees on the ground! We have two litter boxes and keep it clean. My parents take care of him and he even started spraying on the furniture and my mom herself!! They are ready to get rid of him! They are trying everything but he is ruining their home! Please, anyone have any suggestions?!!
