Bloody urine in cats is a fairly frequent problem that may
be caused by several possible diseases, such as urinary tract
infections, urinary stones, tumors, bleeding disorders and more. One
of the most common diseases is feline lower urinary tract disease.
Often the underlying cause remains unknown and the disease is
defined as idiopathic.
Affected cats make frequent trips to the litter box,
attempt to urinate in or out of the box with production of little or
no urine, and often will have blood in their urine. They also lick
their genital area and may complain about their discomfort.
It is speculated that the inflammation of the lower urinary
tract is stress related. Factors such as a recent move, family life
events, addition of new pets, environmental changes or weather
changes may play a roll in the development of the problem.
Males as well as females are at risk, however male cats are
more prone to urethral obstruction and therefore to a life
threatening complication of the disease.
Treatment depends on the disease entity and stage. Removal
of known stressful factors is important. Medical management is aimed
to reduce the inflammation and to avoid bacterial infection. Dietary
management to manipulate the urine composition and acidity is also a
common practice. Obstructed cats are treated promptly to remove the
obstructing material and allow urine outflow.
It is difficult to distinguish between urinary tract
diseases based on the clinical signs, as they are very similar. It
is recommended to seek veterinary care for any cat showing the above
signs as soon as the problem occurs.
