Physical examination revealed severe bilaterally symmetrical masticatory muscle atrophy, a restricted vertical mandibular range of motion of 11\u201312 mm, and a normal body condition score. Skull radiography was normal. A canine ELISA system against unique masticatory muscle fibers (2M antibody titer), was positive at 1:1000 (reference interval &lt;1:100 in dogs, and was &lt;1:100 using serum from five archived normal cats), indicating the presence of cross-reacting antibodies. Owing to the chronicity and clinical severity, corticosteroid treatment did not result in improved jaw mobility, consistent with end-stage masticatory myositis. Masticatory muscle biopsy was declined at initial presentation. However, 1 year later at elective euthanasia, CT ruled out temporomandibular joint osseous restrictions, and masticatory and biceps femoral muscle histopathology evaluation confirmed end stage feline masticatory myositis with normal limb muscle.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Relevance and novel information<\/jats:title>\n                    <jats:p>Masticatory myositis should be included in the differential diagnosis of trismus in cats.
