To lay a foundation for screening the<jats:italic>T<\/jats:italic>.<jats:italic>gondii<\/jats:italic>-felids interaction factors, we have developed a reproducible primary culture method for cat intestinal epithelial cells (IECs). The primary IECs were isolated from a new born cat\u2019s small intestine jejunum region without food ingress, and respectively<jats:italic>in vitro<\/jats:italic>cultured by tissue cultivation and combined digestion method with collagenase XI and dispase I, then purified by trypsinization. After identification, the ds cDNA of cat IECs was synthesized for constructing pGADT7 homogenization three-frame plasmid, and transformed into the yeast Y187 for generating the cDNA library. Our results indicated that cultivation of primary cat IECs relays on combined digestion to form polarized and confluent monolayers within 3 days with typical features of normal epithelial cells. The purified cells cultured by digestion method were identified to be nature intestinal epithelial cells using immunohistochemical analysis and were able to maintain viability for at least 15 passages. The homogenizable ds cDNA, which is synthesized from the total RNA extracted from our cultured IECs, distributed among 0.5\u20132.0 kb, and generated satisfying three-frame cDNA library with the capacity of 1.2 \u00d7 10<jats:sup>6<\/jats:sup>and the titer of 5.2 \u00d7 10<jats:sup>7<\/jats:sup>pfu\/mL.
