Consider the common house cat. Studies show that a significant percentage of cats experience "velcro syndrome" or transport stress just by entering a carrier. A veterinarian treating a cat for idiopathic cystitis (inflammation of the bladder with no known cause) who ignores the cat’s hiding behavior is missing the cure. Veterinary science has now empirically linked feline lower urinary tract disease (FLUTD) directly to environmental stressors. The treatment isn't just antibiotics; it's behavioral modification—adding vertical space, reducing household conflict, and altering feeding routines.
