it's possible a vet can help some know the trick they can use a small probe to 'switch her off' by stimulating mating this triggers ovulation and she will come off heat. Either that or live with a frantic little tart flirting with everything that moves she will stop in a while though just make sure she doesn't get out
Yep, when I got my first cat as a kitten I had no idea they could get pregnant so young. It wasnt until she got stuck in the catflap(I kid you not) and I gently got her out that I realised she was heavily pregnant. Her long fur had done a good disguising job. She gave birth that day!
ooops... my brenda was a stray who was very pregnant... she can't have been more than 6 months old when she had the kittens hence her full title Brenda the tart
just phone the vets - they are not fans of spaying under 5.5 months!!! and suggested Felliway!
I'll give them felliway where the sun don't shine - very little sleep over the last couple of days - Him indoors is all 'oh don't shout at her bless' tell you i will bless him and her together if their not careful!!
Can you maybe try another vet surgery - the earliest date that they will neuter varies from vet to vet. I am so glad that my little girl has been fixed.
