"I won't be selling them at all I don't want any profit from them, I just want to make sure they will be well looked after wherever they are rehomed to... "
Just don't tell me that one of them's a tabby boy or I'll be on your doorstep... ! :o
More to the point, I tend to disagree with the "I don't want any money for them" theory purely because IME in rescue folk tend to put more thought - and hopefully more care - into something they're paying for rather than something they get for free. The ones who will take it if it's free don't tend to be the ones who were looking for a kitten anyway.
What I mean is "Oh, lovely, a tabby kitten, free, I'll have one, what's you're address?" as opposed to, "Hmmm... £80...... then there's the vet bills, the neutering, the vax, the wormer, the insurance, the food... do I want to spend that £80 on a kitten or do I want to spend it down the pub on Friday night?"
It's interesting then to see who REALLY wants a kitten and who would just have one as a knee jerk reaction to cuteness but who wouldn't otherwise have considered owning a cat.
