When can a cat become pregnant?
A cat can become pregnant as soon as she is ready to mate. This is already the case in the fifth month of life, i.e. when the cat is in heat for the first time.
When and how often the rolliness starts depends on the breed, character, weight and living conditions. This emotionally upsetting phase lasts about 9 days and starts over and over again as long as the female cat has not been covered by a suitable sexual partner. During this time the oestrogen level in the body rises and ovulation is prepared. The lady cat will now begin to call emphatically for a male cat.
When your velvet paw emits a beguiling scent, mews louder than usual, rolls more on the ground and suspiciously stretches her butt upwards, sexy time is the order of the day.
Once your cat has found a partner and performed the act of love, she is most likely pregnant. In the wild, female cats usually get involved with different partners. These can fertilise different eggs. This is the reason why the kittens look so different later on.
