Data were collated for the births of 1056 litters from 14 different pedigree breeds and 942 different households. Significant relationships between various outcomes and relevant predictors were assessed by multiple linear regression or logistic regression as appropriate. The overall mean gestation length of 65.1 days varied significantly between the breeds ( P&lt;0.0001), and larger litter sizes were associated with shorter gestation lengths ( P=0.04). The mean litter size of 4.6 kittens also varied significantly according to breed ( P&lt;0.0001). The weight of kittens born alive (overall mean 93.5 g) increased with longer gestation lengths ( P=0.0003), decreased with larger litter sizes ( P&lt;0.0001) and varied between the breeds ( P&lt;0.0001). A total of 8.0% of pregnancies resulted in a caesarean section, with a higher risk associated with smaller litter sizes ( P=0.002). Although the frequency of caesarean sections varied from 0 to 18.5% between individual breeds, breed itself was not shown to have a significant independent effect on this likelihood. A mean of 7.2% of all the kittens were stillborn, which varied according to breed ( P=0.0003), and the risk of a stillborn kitten increased with litter size ( P=0.0001), and with the presence of congenital defects in the litter ( P=0.0002). The mean kitten mortality between birth and 8 weeks of age was 9.1%, and the majority of these occurred in the first week of life. Parturition intervals varied widely. The duration of first stage of labour was less than 2 h in 82.9% of cats. The interval between the birth of the first and last kitten was less than 6 h in 85.7%, but more than 48 h in three cats. A maximum of 48 h was recorded between the births of individual kittens in unassisted deliveries.<\/jats:p>","DOI":"10.1016\/j.jfms.2005.10.003","type":"journal-article","created":{"date-parts":[[2006,1,27]],"date-time":"2006-01-27T10:35:19Z","timestamp":1138358119000},"page":"145-157","source":"Crossref","is-referenced-by-count":82,"title":["A questionnaire-based study of gestation, parturition and neonatal mortality in pedigree breeding cats in the UK"],"prefix":"10.1177","volume":"8","author":[{"given":"Andrew H","family":"Sparkes","sequence":"first","affiliation":[{"name":"Centre for Small Animal Studies, Animal Health Trust, Lanwades Park, Kentford, Suffolk CB8 7UU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Katherine","family":"Rogers","sequence":"additional","affiliation":[{"name":"Centre for Preventative Medicine, Animal Health Trust, Lanwades Park, Kentford, Suffolk CB8 7UU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"William E","family":"Henley","sequence":"additional","affiliation":[{"name":"Centre for Preventative Medicine, Animal Health Trust, Lanwades Park, Kentford, Suffolk CB8 7UU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Danielle A.","family":"Gunn-Moore","sequence":"additional","affiliation":[{"name":"Royal (Dick) School of Veterinary Studies, The University of Edinburgh Hospital for Small Animals, Roslin, Midlothian, Scotland EH25 9RG, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Julia M","family":"May","sequence":"additional","affiliation":[{"name":"Chace Veterinary Group, 26 Essex Road, Enfield, Middlesex EN2 6UA, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Timothy J","family":"Gruffydd-Jones","sequence":"additional","affiliation":[{"name":"Department of Clinical Veterinary Science, University of Bristol, Langford House, Langford, Bristol BS40 5DU, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Claire","family":"Bessant","sequence":"additional","affiliation":[{"name":"The Feline Advisory Bureau, Taeselbury, High Street, Tisbury, Wilts SP3 6LD, UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"179","published-online":{"date-parts":[[2006,6,1]]},"reference":[{"key":"bibr1-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.1136\/vr.151.17.497"},{"key":"bibr2-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.1994.tb03863.x"},{"key":"bibr3-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.1994.tb03951.x"},{"key":"bibr4-j.jfms.2005.10.003","first-page":"145","volume":"124","author":"Gerrits P.O.","year":"1999","journal-title":"Tijdschrift voor diergeneeskunde"},{"key":"bibr5-j.jfms.2005.10.003","first-page":"269","volume-title":"Feline Medicine and Therapeutics","author":"Gruffydd-Jones T.J.","year":"1994","edition":"2"},{"key":"bibr6-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.1136\/vr.136.14.350"},{"key":"bibr7-j.jfms.2005.10.003","volume-title":"Applied Logistic Regression","author":"Hosmer D.W.","year":"1989"},{"key":"bibr8-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.1111\/j.1748-5827.1977.tb05821.x"},{"key":"bibr9-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751-0813.1987.tb15180.x"},{"key":"bibr10-j.jfms.2005.10.003","first-page":"1455","volume":"45","author":"Lawler D.F.","year":"1984","journal-title":"American Journal of Veterinary Research"},{"key":"bibr11-j.jfms.2005.10.003","first-page":"1479","volume-title":"The Cat \u2013 Diseases and Clinical Management","author":"Lein D.H.","year":"1989","edition":"1"},{"key":"bibr12-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.1080\/01652176.1993.9694397"},{"key":"bibr13-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.1016\/S0195-5616(84)50090-4"},{"key":"bibr14-j.jfms.2005.10.003","first-page":"207","volume":"19","author":"Povey R.C.","year":"1978","journal-title":"Canadian Veterinary Journal"},{"key":"bibr15-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.1111\/j.1751-0813.1973.tb06758.x"},{"key":"bibr16-j.jfms.2005.10.003","doi-asserted-by":"publisher","DOI":"10.5326\/15473317-31-5-429"},{"key":"bibr17-j.jfms.2005.10.003","unstructured":"Sayer A., Loxton H.
