We are adopting some kittens, they reach 8 weeks old tomorrow which is generally said to be the minimum age to leave their mum (I am aware that some sources recommend a week or two more) - and the plan was we would collect them tomorrow.
However, apparently they haven't been interested in solid food at all and their mum is still giving then milk regularly. So clearly they aren't quite ready to come to us yet. This is fine and we and the lady who owns mummy-cat both agree we should change the plan and postpone the collection.
However - she's not a breeder (it was an accidental pregnancy, mum was supposed to stay indoors but went off on an exciting adventure) and isn't experienced in knowing the right time, and neither are we.
What indicators are there to look out for to know that the time is right? We don't want to traumatise the kittens or their mum by taking them too early but also have read that kittens settle better into a new environment if they come to it whilst still young.
Any advice?
