breeding

Hello everyone. I have a cat that I wanted to spay after I got her but my mom insists on letting her have a litter once before spaying her. Since my mom is the one who is paying for the vet bills, I have no choice but to listen to her. There are families who want to give the kittens a loving...

My cat went into heat on Thursday the 22th. On Sunday the 25th, her heat cycle ended. On Monday morning (the next day), she puked. Does she have morning sickness? How soon after mating does morning sickness start? How long does a queen's heat cycle last?
