Toksoplasmozis dünyada memeli ve kanatlı türlerini etkileyen ve Toxoplasma gondii tarafından oluşturulan son konağı kedigiller olan sistemik protozoon enfeksiyonudur. Dünya genelinde evcil kedilerde (Felis catus) seroprevalansın %30-40 arasında olduğu tahmin edilmektedir. İnsanlarda parazitin oluşturduğu problemler açıkça bilinmektedir. Bununla birlikte kedilerde parazitin beyin, spinal kord, göz, akciğer, karaciğer, kalp, iskelet kası, dil, adrenal bez ve böbrek gibi hayati organlarda lezyonlar şekillendirdiği ortaya konulmuştur. Ancak, parazitin kedilerde davranışsal değişikliğe neden olup olmadığı incelenmemiştir. Bu derleme ile T. gondii’nin kedilerde insanlardakine benzer davranışsal değişikliklere neden olup olmadığının araştırılması konusuna katkı sunulacağı kanaatindeyiz.
