Urinary tract signs are frequent, and unfortunately, quite often ambiguous as to the cause. They may indicate trauma, bacterial infection, inflammation, the presence of crystals or stones in the bladder or urethra, tumors, or even metabolic disorders.

Due to the small size of the male cat's urinary tract, it can easily become blocked if crystals or heavy mucous "plugs" form.

Bladder stones that are trying to pass may also block male dogs (especially Dalmatians).
