Introduction
Cats (Felis catus) are seasonally polyestrous animals that have multiple estrous cycles only during certain periods of the year.

Developmental Timeline
Twenty-two stages have been described for the prenatal development of the domestic cat.[3]
The following data on early development is based upon the time after copulation[4]
oviduct embryo development
- 64 hours - 1 to 4 cells (17 of 20; 85.0%)
- 76 hours - 5 to 8 cells (18 of 28; 64.3% )
- 100 hours - 9 to 16 cells (14 of 24; 58.3%)
- 124 hours - morulae (15 of 21; 71.4% )
uterine embryo development
- 148 hours - compact morulae or early blastocysts

- There is not much genomic sequencing information available for the cat.
- The entire mitochondrial genome 17,009 bp has been sequenced.
