Long story short, I am 8 weeks pregnant - a very much planned and long awaited pregnancy, following a lot of heartache last year when it was thought I had ovarian cancer. DH and I are over the moon about the pregnancy.
DH is a farmer and logically, as a result, I live on a large farm in a rural village. I have 9 rescue cats (4 of whom are very shy/feral), as well as 4 dogs, several horses, a pig, sheep and chickens as well as over 100 cows. (This is relevant).
My neighbour, a retired kidney transplant surgeon, knows about my pregnancy, as she was the one to give advice over the ovarian cancer issue and when I got the BFP, I rang her to let her know the good news.
She has, however, taken it upon herself to give me pregnancy advice. I'm pretty much of the opinion that everyone is going to give me advice about the pregnancy as they learn about it and I can just keep the advice I want and let it the rest wash over me.
My neighbour doesn't like cats. She doesn't hate them, but to her, they should live outside and "know their place". My cats certainly DON'T "know their place" and rule my house with iron paws. 
DH and I have agreed that when the baby arrives, we will keep the cats out of the babies room and will take precautions with cot nets etc. As far as I am concerned, DH and I have it covered. The cats are staying, and we will not disrupt their lives anymore than we have to with the arrival of the baby. We're obviously going to use common sense, but this is their home too.
This isn't good enough for my neighbour. The first time she "popped over for a chat", she sat on my sofa and told me "I must get rid of the cats, it's worth getting rid of them for a baby". I was polite (i didn't want to offend) and said it was something DH and I would think about for about 10 seconds before I said no fucking way, to DH
The second time (last week), she "popped over for coffee" and sat on my sofa and said "shall I call the shelter so you can get the cats rehomed, I'll do it now if you want". no, you stupid bitch, if I want to rehome my cats, which I don't, I'll use my own extensive rescue contacts thanks very much I again was polite (small village, very few people) and said that at the moment, DH and I were happy to keep the cats while we assessed things.
Yesterday, she "popped in" again. This time she told me that she'd spoken "her friends who were vets" (yes, I know the vet, she is the daughter of another neighbour) who has agreed to PTS the 4 shy cats "to get them off my hands". I told her that I would deal with my own cats, thanks very much, and that I certainly wouldn't be murdering any. She then got huffy, called me unreasonable and informed me that a number of other people agreed with her. 
I am now beyond livid. I want to tell her to fuck off, then fuck off some more now be blunt rather than polite. DH has advised that I tread carefully, because I live in Stepford the village is a small, tight community and I need to be tactful so that relationships aren't strained too much because she carries a lot of clout within the village. (Unfortunately he's right).
Quite apart from me, DH, the GP's (both mine and DH's parents) and my cats vet, are all in agreement that I am perfectly reasonable to keep my cats, providing we take precautions when LO arrives and make adaptations. (e.g. no cats in the babys room). I'm also experienced and trained in cat behaviour, so it's not as if I'm an "ignorant" pet owner.
DH does the litter boxes, I use latex gloves when doing anything remotely "animal care duties". (That includes cleaning out the chickens and ferret, and dog-poo patrol BTW - of which the neighbour has made absolutely no mention).
I know I'm not being unreasonable, my neighbour is, but how the hell do I tell her to fuck off mind her own business politely? I actually need help here!
