|As cats age one of the more common behavioral complaints reported to veterinarians is why cats vocalize or howl, acting very restless at night. While cats do undergo senile geriatric changes, these types of behaviors often indicate an underlying illness or disease.|
Many elder cats who vocalize like this often suffer from high blood pressure. This high blood pressure can be a primary problem or secondary to kidney, thyroid, or heart disease. It is important to have your elder cat examined and blood pressure measured. With early detection high blood pressure can be affectively controlled with medications like Norvasc (Amlodipine). If untreated, high blood pressure in cats may lead to sudden blindness and other internal organ damage.
