Feline Cystitis is associated with Feline Urological Syndrome, Feline Lower Urinary Tract Disease, and Feline Idiopathic Cystitis. The term Idiopathic translates to unknown reasoning. This is because the direct cause of Feline Cystitis is unknown, however certain behaviors have been known to aid the illness once it has been initiated. It can affect any breed of cat. A common nickname for this type of illness is "crystals". This is because tiny crystal or sand like particles form within the urine. This can be treated, however, timing is of the essence. If this illness trails on too long then the cat's life may be at risk. This is why it is important to scrutinize one's cat when their behavior is especially peculiar.
