Increased Thirst and Urination in Cats

Increased thirst and urination are symptoms of a number of common diseases, especially in cats over 10 years of age.  The medical terms for these symptoms are polyuria (excessive urine production) and polydipsia (excessive thirst).

When a cat presents at Hampton Veterinary Hospital for increased thirst and urination, as always, one of our doctors will perform a thorough physical examination.   Regardless of the cause, many times our feline patients with increased thirst and urination will also present with any combination of the following non-specific symptoms or findings on examination:

  • Weight loss and muscle atrophy
  • Increase or decrease in appetite
  • Vomiting
  • Change in energy level
  • Heart murmur

The most common diseases we see inolder cats that cause increased thirst and urination are:

These three diseases, as well as a number of less common causes, can easily be tested for by submitting blood and urine samples for a chemistry profile, complete blood count (CBC), thyroid level(s),and urinalysis.  If lab work rules-out these common medical conditions in older cats, then we typically proceed to taking x-rays and/or performing an ultrasound.

Aging, whether it be with ourselves or our four-legged loved ones, can be scary.  It is not uncommon for many people to avoid the doctor because they do not want to learn about medical issues that might shorten lives.  However, each of these diseases listed above can usually be treated to improve quality and length of life in our feline friends.  This is especially true if we screen for such issues and start treatment sooner rather than later.  So, please contact us should you be concerned about an increase in thirst and urination or any other medical issue your pet may be experiencing.
