| + | *Stage 1: this is the preparatory stage, starting at the onset of regular uterine contractions followed by cervical dilatation and the foetus assuming the correct disposition for passage through the birth canal. |
| + | *Stage 2: the expulsive stage, characterised by the onset of abdominal contractions which together with uterine contractions lead to foetal expulsion |
| + | *Stage 3: separation and expulsion of the foetal membranes. In polycotous species second and third stages are often inter-mixed. |

− | During the last week of pregnancy, the queen seeks a nesting area. This is usually a quiet, undisturbed spot but some house cats will demand more human contact.Mammary development becomes noticable in the last week of pregnancy, especially in maiden cats. Rectal temperature may fall a few days before parturition, but this is not a reliable indicator.

− | === Stage 1 ===
| |
− | | |
− | * Restless
| |
− | * Frequently visits the site for kittening
| |
− | * Occasionally lies down and will strain unproductively.
| |
− | | |
− | === Stage 2 ===
| |
− | | |
− | * Straining in lateral recumbency.
| |
− | * Rapid expulsion of kittens with a short interval between each birth.
| |
− | * Parturition usually complete within a few hours.
| |
− | * If the queen is alarmed, this may disrupt the pattern and she may move the kittens to a new area before parturition resumes.
| |
− | * Soon after birth the kittens begin to suckle.
| |
− | | |
− | === Stage 3 ===
| |
− | | |
− | * Placentae usually expelled still attached to the foetus or shortly afterwards.
| |
− | * Consumed by the queen.
| |
− | * Breakdown of marginal haematoma releases biliverdin, giving the discharge a brownish colour.
