Quite often the second pregnancy is completely different. I had really sore breasts, nausea and tiredness with my first, with the second I had none of these symptoms despite it being a twin pregnancy.
normally around 16 weeks, but they say it depends whether its your first or second pregnancy, as on your first you don't really know what you are looking for.
Likely an operation.
Yes it is, my first pregnancy was fine, this one i have gest diabetes, thrombosis and PGP.
Yes, it is.
Every pregnancy is different. Just because you had something, say nausea, with the first, doesnt mean you will for sure with the second
Second cat pregnancies are easier for the cat than the first.
The same as the first time
The first, second and third trimester.

Probably not - the first sire's DNA would be long gone from the uterus before the second pregnancy was started.
