Introduction
Cats (Felis catus) are seasonally polyestrous animals that have multiple estrous cycles only during certain periods of the year.
The cat genome was initially sequenced in 2007[1] and has been recently annotated in August 2014.[2]

Developmental Timeline
Twenty-two stages have been described for the prenatal development of the domestic cat.[6]
The following data on early development is based upon the time after copulation[7]
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
- days 12-14 - implantation occurs
Oocyte and Spermatozoa
The following scanning electron micrographs are from a recent paper on fresh and frozen cat oocytes.[8] Scale bar is 10 microns.
Genetics
Lineage: Eukaryota; Opisthokonta; Metazoa; Eumetazoa; Bilateria; Coelomata; Deuterostomia; Chordata; Craniata; Vertebrata; Gnathostomata; Teleostomi; Euteleostomi; Sarcopterygii; Tetrapoda; Amniota; Mammalia; Theria; Eutheria; Laurasiatheria; Carnivora; Feliformia; Felidae; Felinae; Felis; Felis catus
The cat genome was initially sequenced in 2007[1] and has been recently annotated in August 2014.[2]
- Mitochondria - entire mitochondrial genome 17,009 bp has been sequenced.

Early Development
Hill and Tribe in 1924[9] wrote a detailed description of oocyte to blastocyst development in the cat.
Placenta
- zonary placenta without cotyledons
- relatively small marginal hematoma
- materno-fetal barrier is endothelial-chorial
- superficially invasive into the endometrium but not into the myometrium
- placental labryrinth has characteristic giant cells
Placental cord
- two pairs of vessels in the cord
- two arteries and two veins
- allantoic duct
- cord average length 2 to 3 cm and 0.3 to 0.5 cm in diameter
- inserts at the margin of the zonary organ
- no spirals, no vitelline duct, and no additional vessels or structures
