Cat High Blood Pressure (hypertension)

In both humans and cats, high blood pressure often has no signs or symptoms. This makes the condition very dangerous since it can go unnoticed. High blood pressure has harmful effects on the following four main body systems.

When blood pressure is too high, damage to these systems occurrs, but signs of damage are not always observed right away.

• Heart: trouble breathing, signs of stroke including dragging a limb or both hindlimbs, collapse
• Brain: unexplained changes in behavior including increased meowing and howling
• Kidneys: increased drinking, large urine clumps in the litter box, vomiting
• Eyes (retinas): Sudden blindness including bumping into furniture, missing jumps, walking along walls for direction
