hi, 1 of my cats is pregnant, no idea when she got pregnant as didnt evn know shw was in hear. her tummy is alot bigger than normal, how i can i tell how long she has got to go without taking her to the vet?
She got pregnant because she isn't spayed and she goes out. Some cats are silent callers and most of them become escape artists when in call. They also call about every 3 weeks except during the winter (in the UK) until they get pregnant, so relying on keeping her in for contraception is a pretty tall order. She can also get pregnant again while her kittens are tiny, so you need to keep her in until they are weaned - about 10 weeks - and you can get her spayed.
Since she is showing she is certainly in the second half. If you can feel kittens moving she's probably in the last 2 weeks. Note the word 'probably'. The only reason I would take her to the vets is for worming - the vet can't give you a precise due date.
