Oldcat (17 Years) sits at the top of the stairs when we are downstairs and YOWLS. Really horrible mournful yowls which panic the crap out of me. She's on meds for early kidney disease but seems to be responding well. She only ever does it when we're downstairs. Is she trying to get us to come upstairs and fuss her, as she likes it up there, or is the poor old thing going doolally, or is there something else? I did think maybe a UTI but she doesn't do it when she wees, only when she's upstairs without us.... anyone got any ideas?
