I don’t think she is abandoning it for she only grabs this kitten and she takes it to a hiding spot and tries to feed it but then she just leaves it there
Hi our Black Persian had 6 kittens a week and a half ago and one of the kittens is half the size of all the others.
Mum often picks her up and takes the little one away from the rest and hides with it.
She does try to feed it by itself.
She also leaves it out of the nest like she is neglecting...
