Tip on What to do if Your Cat is Going in and Out of the Litterbox
Cats can get a variety of urinary problems including a urinary obstruction
or Feline idiopathic cystitis
(FIC). A common symptom of these diseases is a cat that goes in and out of the litterbox frequently straining or producing little to no urine.
Other signs include: Blood in the urine
Increased frequency of urinations
Straining to urinate
Distressed meowing while urinating
Increased grooming of the genital region
Urinating in inappropriate locations (often in cool smooth surfaces such as bathtubs and sinks).
These symptoms can be mistaken for constipation. Frequent unsuccessful attempts to urinate, distressed meowing while attempting to urinate, lethargy, loss of appetite, vomiting and reluctance to move are symptoms that may signal urinary obstruction in a male cat and may constitute a medical emergency.
Call your veterinarian immediately if you think your cat is showing these symptoms. Complete urinary obstruction can develop into a life-threatening emergency with 48 hours.
