Therefore, blood typing is necessary to reduce the risk of hemolytic reactions, but so far, no studies have been carried out to establish the incidence of common blood types in cats from Angola. Therefore, the objective of this observational study was to assess the occurrence of cat blood types in a non-pedigree feline population of Luanda province in Angola, a country in Sub-Saharan Africa, and to determine the risk of a mismatched transfusion and of neonatal isoerythrolysis (NI). Of the 127 cats tested (71 males and 56 females), including diseased and healthy cats with ages ranging from 8 months to 17 years, 94.9% were type A and 5.1% were type B. No type C cats were found. The calculated risk of a mismatched transfusion was 9.64%, and the proportion of mating risk for NI was 4.82%. Our results, although similar to those reported globally, differ from data described in other studies on the African continent. According to the results, blood typing is recommended prior to transfusion or matting.<\/jats:p>","DOI":"10.3390\/vetsci12040357","type":"journal-article","created":{"date-parts":[[2025,4,14]],"date-time":"2025-04-14T06:18:36Z","timestamp":1744611516000},"page":"357","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Observational Study on the Distribution of Cat Blood Groups in a Non-Pedigree Population in Luanda, Angola"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-7114-6918","authenticated-orcid":false,"given":"Ana C.","family":"Silvestre-Ferreira","sequence":"first","affiliation":[{"name":"Department of Veterinary Sciences, University of Tr\u00e1s-Os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Animal and Veterinary Research Centre (CECAV), University of Tr\u00e1s-Os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Science\u2014AL4AnimalS, 1300-477 Lisboa, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3976-1619","authenticated-orcid":false,"given":"Hugo","family":"Vilhena","sequence":"additional","affiliation":[{"name":"Animal and Veterinary Research Centre (CECAV), University of Tr\u00e1s-Os-Montes and Alto Douro (UTAD), 5000-801 Vila Real, Portugal"},{"name":"Associate Laboratory for Animal and Veterinary Science\u2014AL4AnimalS, 1300-477 Lisboa, Portugal"},{"name":"Center for Investigation Vasco da Gama (CIVG), Department of Veterinary Sciences, Escola Universit\u00e1ria Vasco da Gama (EUVG), 3020-210 Coimbra, Portugal"},{"name":"Department of Veterinary Clinics, School of Medicine and Biomedical Sciences, ICBAS-UP, University of Porto, 4050-313 Porto, Portugal"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1427-8831","authenticated-orcid":false,"given":"Ana C.","family":"Oliveira","sequence":"additional","affiliation":[{"name":"Casa dos Animais Veterinary Clinic, Luanda 298, Angola"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 R.","family":"Mendoza","sequence":"additional","affiliation":[{"name":"Casa dos Animais Veterinary Clinic, Luanda 298, Angola"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Maria Garcia","family":"Aura","sequence":"additional","affiliation":[{"name":"Casa dos Animais Veterinary Clinic, Luanda 298, Angola"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Josep","family":"Pastor","sequence":"additional","affiliation":[{"name":"Department of Animal Medicine and Surgery, Universitat Aut\u00f2noma de Barcelona (UAB), Bellaterra, 08193 Barcelona, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"287","DOI":"10.1111\/j.1365-2052.1981.tb01561.x","article-title":"The AB blood group system of cats","volume":"12","author":"Auer","year":"1981","journal-title":"Anim.
