Blocked Cats – What does that mean?

The term “blocked cat” actually refers to the obstruction of the urethra in a male cat.  (But it is important to remember that it can happen to both dogs and cats, and also in females – just less commonly). The urethra is the tube that drains urine from the bladder and when it becomes blocked, a cat cannot pass its urine.  This is an emergency situation and needs to be addressed immediately.
