Is my cat going into labour?

Put her in a room by herself (with just you), NO OTHER PETS unless you want her to perhaps kill her kittens due to anxiety. She should have a litter box nearby, and water.

By "box" do you mean litter box? You don't want her to have her kitten in there, do you? Prepare a kennel or cardboard box by lining it with newspapers. Sit beside the box so she will feel safe. You should be seeing contractions (straining) soon, and it won't be long until the first kitten appears. If the mother doesn't remove the sac from the kit's face right away, do that yourself so the kit can breathe. A lot of kittens suffocate because the mom cat is too busy cleaning herself to get the sac off in time....

If she's straining for more than half an hour with no results, PHONE your vet. A kitten might be stuck.

Change the papers between kittens to keep the nest clean.

Yes she is going into labor. My cat had most of the same signs. Another sign is her breathing and making loud noises. You should check to see if she is breathing heavily because that is exactly what happened to my cat so that is also a sign to look out for. Also make sure you have a box there for her and line the insides with some cloth or a towel for her to be in. Make sure the box is big enough to fit her and her kittens, you don't want the box to be too compact for her.

When she is giving birth though don't touch her or anything but leave her to give birth. The kittens will come out one at a time and it may be a long or short process but make sure you are there just in case, my brother was. But good luck on her giving birth which she will be doing now if not shortly and here is a link for you to look at and scroll down to see the parts about a cat in labor. It will give you a lot more detail. Congrats!

cats are often very nicely without help. basically save checking on her to make optimistic she is effective. it could take quite a few hours for each and all the kittens to be born. the main suitable factor to do suitable now could be to make an emergency plan, alongside with finding up the tackle and quantity to an animal sanatorium that could be open in one day in case she needs help. locate the instructions for a thank you to get there so which you will no longer get misplaced in case you may desire to get her to a vet, and have a container with some previous towels or blankets in it to place her and any kittens she could have had in. this way you're waiting to get her help if she needs it.
