I have a question concerning  Cat

Here you will find answers by our team of vets to FAQs to frequently asked questions in relation to Cat, Heat Pregnancy Gestation

How long and how often is a cat on heat during the year?

How often and for how long is a cat (I have a domestic, 6 years old) on heat during the year? Mine looks like she has been on heat permanently for about two weeks. We now would like to have her castrated. She has been peeing everywhere for two weeks (she didn’t do that before).

Cats normally have a reproductive phase in Spring and one in Autumn. Several cycles can follow each other during these periods. A cycle takes 2 to 3 weeks if the cat is not impregnated and can even last 6 to 7 weeks if the cat has a false pregnancy after unsuccessful covering. Being on heat for 2 weeks is therefore nothing unusual. Many cats become unclean during this time. This un-cleanliness as well as the on heat symptoms of course stops directly following castration. Often, it can take up to 6 weeks until the last on heat symptoms disappear (this phenomenon probably depends on physical hormone control in the pituitary gland and the interbrain). I therefore advise you to be patient up to the castration date as this is imminent and the chances are very high that the un-cleanliness disappears together with the on heat phase.


How can I tell if my cat is pregnant? What are the signs to look out for?


If your cat was in heat and had access to a tom (unneutered male) cat, the likelihood that she is pregnant is very strong. A pregnant queen will show both physical and personality changes which will become more evident around three weeks after breeding. The gestation period for cats runs from 60 to 67 days. I like to use 63 days as an average, because it is easier to equate with human gestation (nine weeks vs nine months).

Physical Changes in a Pregnant Cat

·         Heat Cycles Cease: This will be the first sign you may notice. If a cat has been suffering heat cycles every 10 days to two weeks, and suddenly stops, it is very likely she is pregnant.

·         Nipples Swell and Become Rosier in Colour: Breeders call this “pinking,” and it may be the first physical sign you will see.

·         Increased Appetite in a Cat: A pregnant cat will show an increased interest in food. After all, she is not only eating for herself, but for several foetuses.

·         Possible Vomiting: Pregnant queens may be subject to a few bouts of “morning sickness,” much as human mothers-to-be. This in itself is not cause for alarm, but if it continues or is frequent, veterinarian intervention is needed.

·         Abdominal Enlargement: Sometime around the fifth week of pregnancy, a pregnant cat’s abdomen will start to swell noticeably, and it will continue to enlarge until time for birthing.

Personality Changes in a Pregnant Cat

·         Increased Affection: Your cat may become more affectionate than normal and frequently seek out your attention. By all means, give it to her!

·         “Nesting” Activities by a Pregnant Cat: This is not an early sign of pregnancy, but as the time for partruition (birth) approaches, your pregnant cat may seek out quiet, private places for birth to take place.

Clinical Diagnosis of Pregnancy in Cats

If your queen has had regular veterinary care, and the previous signs of pregnancy are evident, it may not be necessary to have an “official” diagnosis by a veterinarian, unless you have reason to fear something is wrong. However (and this is a big consideration), if your intent is to spay her, it is probably better that your veterinarian knows exactly what to expect.

·         Palpation of the Cat’s Abdomen: Your veterinarian may be able to feel fetuses by palpating (feel by gently pressing) your queen’s abdomen, usually around the 17th-20th day of pregnancy.

·         Ultrasound of Your Cat’s Abdomen: This diagnostic tool may detect fetuses as early as the second week of pregnancy, and heartbeats may be detected sometime after the third week.

If your resident (or rescued) cat is indeed confirmed pregnant, some serious decision-making time is at hand. See the next article in this series for help with that decision.
