1. Veterinary Care For Pregnant Cats

Cats that are a healthy weight shouldn’t require much veterinary attention during pregnancy, but should still pay the vet a visit.

Most pregnant cats don’t actually require a lot of veterinary care. It is a good idea to book a vet visit to make sure she is healthy and has a good body condition score. This means that she is not too fat or thin. Your veterinarian will guide you through what checkups she might need, and prepare you for what to expect during her pregnancy and birth.

Ideally, cats should be fully vaccinated and up to date with flea and worming treatments before becoming pregnant. If your cat has not had flea or worming treatment, your vet will be able to advise on which products are safe to use. Most vaccines are not safe to use during pregnancy.

2. Nutrition for Pregnant Cats

Now that you know your cat is definitely pregnant, it is a good time to transition her onto a diet that will meet her extra needs. Do this gradually by adding more of the new food each day for about a week to avoid a tummy upset. A high-quality kitten food is usually a good option and will provide both the mother cat and her kittens with all the nutrients they need. You can also offer the same food to the kittens once they begin to eat solid food.

While your pregnant cat is eating for two (or three, four… maybe even 10!), it’s important not to over-feed her. Aim to increase her food by about 25% as the pregnancy progresses. Be prepared to increase or decrease this, depending on her body condition score. You don’t want her to become over or underweight.

As she progresses towards her due date, the growing fetuses may start to press on her stomach. This can make it uncomfortable for her to eat too much in one go. So, it is a good idea to offer frequent smaller meals (about 4-6 times a day) to ensure she is getting enough.

3. Preparing the Environment for Your Pregnant Cat

Cats often don’t need help when giving birth, but it’s important to keep a watchful eye on the birthing.

In the last few weeks of pregnancy, it is a good idea to keep your feline mom-to-be inside to make sure she is somewhere safe when she gives birth.

She will begin to look for somewhere safe to deliver her kittens – this is called nesting. You can help by providing a private, quiet place with lots of soft blankets and somewhere dark to hide away – like a cardboard box.

When the big day arrives, you may notice her becoming restless, panting, and being more vocal than usual. She may also have some discharge from her vulva. As hard as it is, try not to disturb her and keep a careful watch from a safe distance. The more relaxed she is, the better.

Most cats will give birth on their own, but if you are worried about her or any of her new kittens, then call your veterinarian right away.

Neutering cats at the appropriate age is the best way to keep unwanted pregnancies from occurring.

The best way to prevent pregnancy in cats is by neutering them before they are sexually active. This can be as young as 4-months-old.

Neutering will not only prevent unwanted litters but reduce your cat’s risk of mammary (breast) cancer and a life-threatening womb infection called a pyometra. Speak to your veterinarian about getting your cat neutered.
