why

And now, out of the blue, you strongly suspect that you're going to be a grandparent to a litter of kittens and you have no idea when that might be.
So, just how long will it be before you can gaze on your tiny new kittens?
On average, feline pregnancy lasts for 63-65 days but can be anywhere from 58 days to 70 days long. In 'real money', that's around nine weeks.
But as chief midwife-in-waiting, unless you have a good idea when your promiscous puss-cat was consorting with the local toms, you will only be able to make a rough guess at the expected delivery date.
It's much more likely that you will miss the fact that your lovely cat is pregnant until she is 5 or 6 weeks into her pregnancy and the signs become fairly obvious.
By the time you begin to recognise the physical changes in your cat she will already be over halfway through her pregnancy.
If you are very vigilant, you may have noticed your cat's nipples looking significantly pinker than usual. This occurs around 3 weeks into the pregnancy as her milk glands begin to change in readiness for full-scale milk production when her kittens arrive.
Around the same time, your cat may go off her food. Could it be puss-cat morning sickness perhaps?
Mind you, it's not unusual for any cat, pregnant or not, to go through fussy phases in their eating, so it's not very likely that you would particularly associate this with pregnancy.
Unless you have experienced a previous pregnancy with your cat, it is highly unlikely that you will attach any significance to these subtle changes.
It will not be until there are only 21-28 days to go before the birth that you will become sure that your lovely cat is pregnant.
Of course, as a loving and responsible cat owner, you will feel that it is your duty to make sure that you are fully prepared to help your cat give birth safely and calmly. It is up to you to arm yourself with the knowledge you will need to care for your newborn kittens and their mother to the best of your ability by finding a comprehensive ebook that will easily guide you through all the stages of pregnancy, labor, birth and nursing.
But above all, just enjoy the thought that very soon you will become a kitten grandparent!
