AbstractDomestic cats are frequently used as a research model for felid species that are threatened withextinction. Until now, the development of feline embryos has been evaluated using both classicalobservation methods and time-lapse monitoring (TLM). Blastocyst collapse observed using time-lapsecinematography is used as a predictor of blastocyst quality and is closely related to implantation po-tential. The aim of this study was to determine the relationship between the quality of domestic catblastocysts obtained afterin vitrofertilization and the frequency and duration of collapse, and ofhatching.There was a significant difference in the average number of collapses and weak contractions betweengood and poor quality blastocysts. There was no significant difference between hatching and non-hatching blastocysts in terms of blastocyst cavity formation time or average number and duration ofcollapse.These results showed that the time of cavity formation was not related to blastocyst quality. Thenumber of collapses and the occurrence of hatching were positively related to blastocyst quality, andpoor quality blastocysts have, as a consequence, a reduced potential for implantation. TLM plays a sig-nificant role in cat embryo evaluation.
