Meet BSH mother cats and mixed breed kittens

I am trying to rehome all my grandmothers cats as she is struggling to look after them due to age. Last year my grandmother took in a pregnant British Short Hair stray cat. My grandmother rejoined some of her kittens but kept the ones she couldn’t rehome. The BSH and one of her kittens has now had more kittens so we are looking to get all of them rehomed as my grandmother cannot cope with looking after them all
