This study was carried out to evaluate cystitis of cats with idiopathic lower urinary tract disease but without signs of the disease at the time of the study. Histopathologic and morphometric analysis of the urinary bladder were done in 15 cats, eight with the disease but with no clinical signs and seven healthy cats. There was bladder mucosal and muscle layers thickening with intense mononuclear inflammatory infiltrate, subepithelial petechiae, hyperplasia and epithelial wrinkles among the cats with the lower urinary tract disease, these findings suggest chronic cystitis.
