MY CATS PREGNANT AND UNDER NO CIRCUMSTANCES WILL MY MOM LEMME KEEP HER BABIES

my cat went into her first heat cycle last month(dk if that's the correct way to say it but yea) and I've been waiting for her to go in it again but she didn't (cus I had to get her spayed after this 1) after abt 3 weeks I grew suspicious that she's pregnant and just confirmed she is with even my sister and friend telling me she looked "fat" or "round at the belly". Well I haven't told anyone yet obviously but I've no idea what to do. I'm taking her to the vet today and will definitely get her spayed asap.

I would've gotten her spayed now (as in aborting the kittens) but according to various sources that's quite dangerous so I don't wanna attempt that.

Any tips would be appreciated because I literally have NO idea what to do.
