First question: Where does this blockage happen? Answer: In a small tube known as the urethra that connects the bladder to the outside of the body.
Next question: Why is this blockage a problem in just the male cats? Answer: Male cats urethral tube is much smaller than female cats, making it easier for bladder crystals to plug the tube.
What causes crystals? A diet high in the mineral magnesium, urine that is not acidic enough, or something as simple as the cat not drinking enough water can lead to blockage.
(1) Keep the cat drinking lots of water
(2) Stay on a special diet for bladder problems
(3) Keep your cat’s weight under control.
