Neurologic examination revealed a C1\u2013C5 myelopathy. Computed tomography of the vertebral column and thorax revealed incomplete ossification of the C2 and C3 vertebrae and lung bullae. After 4 wk of conservative management, the client reported a return to normal ambulation with reluctance to jump up. To the authors' knowledge, this is the first report of a feline case of incomplete ossification of cervical vertebrae. The cervical malformations outlined in this report are differentials to consider in cases of acute-onset tetraparesis in cats.<\/jats:p>","DOI":"10.5326\/jaaha-ms-6865","type":"journal-article","created":{"date-parts":[[2019,8,21]],"date-time":"2019-08-21T09:44:19Z","timestamp":1566380659000},"page":"256-260","source":"Crossref","is-referenced-by-count":1,"title":["Multiple Cervical Vertebral Malformations in a 21-Week-Old Kitten"],"prefix":"10.5326","volume":"55","author":[{"given":"Barnaby Luke","family":"Dean","sequence":"first","affiliation":[{"name":"From Southern Counties Veterinary Specialists, Ringwood, United Kingdom (B.L.D.); and Langford Small Animal Hospital, Bristol, United Kingdom (C.S., F-X.L., C.W-S.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Caroline","family":"Smith","sequence":"additional","affiliation":[{"name":"From Southern Counties Veterinary Specialists, Ringwood, United Kingdom (B.L.D.); and Langford Small Animal Hospital, Bristol, United Kingdom (C.S., F-X.L., C.W-S.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Francois-Xavier","family":"Liebel","sequence":"additional","affiliation":[{"name":"From Southern Counties Veterinary Specialists, Ringwood, United Kingdom (B.L.D.); and Langford Small Animal Hospital, Bristol, United Kingdom (C.S., F-X.L., C.W-S.)."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christopher","family":"Warren-Smith","sequence":"additional","affiliation":[{"name":"From Southern Counties Veterinary Specialists, Ringwood, United Kingdom (B.L.D.); and Langford Small Animal Hospital, Bristol, United Kingdom (C.S., F-X.L., C.W-S.)."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"3280","reference":[{"issue":"5","key":"bib1","series-title":"Vet Clin North Am Small Anim Pract","first-page":"951","article-title":"Congenital spinal malformations in small animals","volume":"40","author":"Westworth\n              DR","year":"2010","unstructured":"Westworth\n              DR\n            , SturgesBK.
