Blocked Cats—Urethral Obstructions are Emergencies

Male cats can easily develop obstruction of the urethra which is the tube draining urine from the bladder out of the penis. Obstructions are often the result of plugs of inflammatory material, mucus, crystals, small stones (called calculi) that have formed in the kidneys and have passed down into the bladder (see urinary stones). The cause of the inflammatory materials and stone formation is not well understood, though viral infections and diet may play a role. Other causes are reported such as cancer, previous injury causing scarring, and trauma are also reported. Early neutering of cats does not cause reduction of urethral size as in some other species.


Seizures—When Is It an Emergency?

A Single Breakthrough Seizure

It is a lucky pet that never has another seizure after beginning medications; but an occasional breakthrough seizure (as disturbing as it may be to watch) is rarely of serious concern. In most cases, one can simply give an extra dose of the oral anti-seizure medication that has been in use and consider the episode over with. The veterinarian should be appraised of the situation and the medication regimen evaluated to see if adjustments should be made to prevent further breakthrough seizures in the future.
