cat breeding

Question
I was wondering if a queen can get pregnant from just one(few hours)session with a tom?  They were pinned up together for about four hours and I know that she was ready with out a doubt every time anyone would pet her she would be down on her belly with her butt up.  I have a couple of kids just dying to know if there may be kittens on the way. Thank you for your time and help.

Answer
Michelle,

Yes, they most certainly could have done the deed.

Start counting from the day after the breeding and at day 21, her nipples should be prominent and bright pink, if, indeed, she is pregnant.  This only lasts a couple of days,

Normal gestation in domestic cats is 65-67 days with 63 days being a normal minimum and 69 days being a normal maximum.

Also, when you ascertain she is definitely pregnant and have a range of due dates, talk to your vet to make arrangements in case things go wrong, especially after office hours!

Best regards... Norm.
