Understanding Feline Cystitis

Cystitis means irritation of the bladder. Feline Idiopathic Cystitis is a common issue in cats, falling under FLUTD – Feline Lower Urinary Tract Disorders. Read more about FLUTD here.

Symptoms of Cystitis in Cats

  • Cats straining to urinate
  • Blood in urine or pink-tinted urine
  • Excessive licking at the genital area
  • Increased frequency in urination
  • Avoiding the litter box
  • Peeing in unusual places like bathtubs, sinks, or floors
  • Only small amounts of urine passed
  • Crying out in pain while urinating

Treatment for Cystitis

Vets often prescribe antibiotics. Other treatments might include anti-inflammatory drugs for severe inflammation.

Why Cats Pee Everywhere

Cats might associate urination pain with the litter box and seek new places to pee. The coolness of bathtubs or tiles may also offer relief.

Give Your Cat a Chance

Inappropriate urination is a top reason for cat surrenders. Before taking action, visit your vet to check for Feline Cystitis or a Urinary Tract Infection.
