What are the good/bad signs to look for during my cat’s labor?

Some cats may display a great amount of agitation during labor, though this does not always indicate physical distress. Some agitation during birth is normal. Symptoms such as profuse bleeding, especially if the blood is bright red in color, foul-smelling or off-color discharge, or listless or lifeless behavior on the part of the mother may indicate a serious problem and your vet should be called. If your cat has given birth to a few kittens, and you suspect that there may be more which do no emerge within an hour’s time, your vet should be contacted. It is possible that some of the kittens have become stuck, or that the mother’s uterus has stopped contracting.
