How long until my cat has kittens?

9 weeks usually. though my cat went into heat 2 weeks after she was pregnant which really through me off.about a week before she had them she started sleeping most of the time and was extremely affectionate. I could feel them moving around or kicking about 2 weeks before she had them. she started to get bigger like 4 weeks after getting pregnant. she went from being an indepedant cat to being a “diva or queen” had to lay on me at all times lol very cute. anyways its to hard to say you just have to be patient. have a box ready for her with shredded newspaper and a towel or sheet on top of the shredded newspaper ready. I put it in my closet. my male cat always tried to get into the box so I had to close the closet door and remind the momcat it was there for her. when she started to go into labor, she acted anxious and was breathing harder and left her mouth open and panted like a dog. thats when I took her into the closet…big walk in closet btw…and shut the door. she wanted me to be there. she became so affectionate towards me throughout her pregnancy it was like she choose me to be her coach lol it was amazing and the kittens were absolutley adorable!!! I put a litter box and a food/water dish in the closet with her… she didnt come out till about 4-5 days later. they will figure it out on there own…cats have been around for a VERY long time and with the pet population out of controll believe me if its meant to be its meant to be.. just be cautious of what your getting yourself into…be prepared to find amazing homes and spend a lot of money on them…theey are like newborn babies and unless you are spine-less you will become maturnal to them. its an amazing bonding experience. please pay attention to your cat and how she acts.. you will know whats going on its human nature… hope this helps… -mike
