Kitten from neighbour -unvaccinated feral dads?

[AdultHumanFemale]

My neighbour's cat has had a surprise litter of kittens, and since our elderly cat died last year, we have been thinking of getting another cat. We've got our previous two from rescue centres, so know very little about getting a cat from kittenhood.
My worry is that one of the kittens' fathers could be one of the many feral strays around here who are most likely unvaccinated and may carry infection which may have been passed on to the kittens? I don't know whether mum is vaccinated either, only that she got pregnant before neighbour had a chance to spey her. Does transmission of infection work like this? Our old cat died of cancer and the vet said that she had been more susceptible to it as she had suffered badly with cat flu in her early life before being brought to the rescue, and so had compromised immunity for life .

Cats are resilient and it's survival of the fittest. If you do decide to have a new kitten then just make sure she is checked by vet and given appropriate vaccinations. Don't get a moggie if you really desire a purebred ( which probably have more genetic issues anyway).

We had 2 lovely crossbred kittens that we lost to feline leukaemia at a year old. We had them fully vaxxed when we got them and they lived indoors so the vet said they could only have caught it from their mother. It was heartbreaking to lose them so young.

For that reason our next kitten came from a proper breeder and any future cats we will have fully vet checked before taking them home.

Thank you both. I'm sorry about the loss of your kittens, Weasel , that is so sad.
I really like a good moggy, and have never considered a pedigree cat. I'll chat to my neighbour and see what his cat's vaccination status is, and see if he's is open to a vet check if we are interested in one of the kittens.
Thanks again.
