Homing mum and kittens

[Whatoflife]

I work with a small cat rescue charity.
Is it advisable to home a single kitten with mum? (5 kittens total)
I’m sure I’ve read that this is no longer advisable (in the same way that litter mate puppies shouldn’t be homed together) but I can’t find any decent research apart from peoples personal experience of ‘worked fine for me’.

Our local biggish rescue won't re-home mother and kitten together as they say it too often doesn't work out.

Thanks @Whatoflife for an interesting discussion.

My last rescue was one half of a middle aged sibling pair who did not get on at all.

Latest was a young semi-feral honey badger stray picked up with her 2 6mo kittens who were fully feral, and the decision to split them so she could have the chance to live in a home was absolutely the right one as she's turned into a delightful, if bitey and a bit quirky and needy, sweetheart.

We rehomed a mum and male kitten 11 years ago. It was armageddon for the first couple of years and then they settled into a bit of a detente and have been there ever since. They've never curled up together, groomed (since the male was a kitten) or done anything bar tolerate each other.

Interestingly we added a third cat a year ago and they both loathe him. So I think we just have a pair of grumps!

We adopted mum and kitten, mum was very young and kitten was the only one of the litter who survived. It worked well when kitten was younger, once she got to about 8 months mum was clearly thinking surely you should have moved out by now! They get along ok (kitten generally backs down unless there's food involved!) but mum keeps herself to herself whereas kitten would prefer more interaction.
