my cat has recently been diagnosed with hypertrophic cardiomyopathy. she is on 2 different heart meds and was on a diuretic but was taken off that due to he kidney enzyme levels being high. she keeps licking her lips.. she never did that before.. is this maybe a kidney problem or heart .. she drinks lots of water anyway.. always has as she prefers to eat dried food although does eat wet food now and then.. does anyone have the same situation?
