When a female cat has "intercourse" with a male cat and becomes pregnant. Cats give birth 63 days (give or take a few days) from the date of conception.
That makes your conception date roughly January 14th 2009. However, this date is give or take a couple of days. It all depends on when you actually ovulated.
Cats will give birth 62 days (plus or minus 2 days) from the date of conception.
It depends on whether July 22nd was the due date of the baby too. It would be roughly October 28th, give or take a few days. However, it is difficult to accurately say when a conception date is. Therefore, I suggest talking to your doctor, midwife or obstetrician about it.
That would make your estimated conception date August 1st 2011. However, this date is give or take a few days. It also depends on when you ovulated.
I will assume that you are talking about January 1st 2012. If so, your estimated conception date is April 9th 2011. This date could be a couple of days out though. It also depends on your menstrual cycle.
It depends on when the due date is, rather than when the baby was born. However, if that was also the due date it would make the conception date roughly October 28th 2005, give or take a few days. However, it's difficult to accurately say when a conception date is.
