Hi Janey - i'm not sure, looks like probably not....
I've asked her to move them into the dry shed with a blanket, food and water. She's going to take them to the vets in a couple of weeks for a de-flea and de-worm and then get the mum cat spayed after that. She may be willing to take a couple of the kittens i they settle with her ow cats and i've asked her to socialise the kittens as much as she can so they don't turn semi feral. In the meantime i've asked her to contact every rescue centre listed on CC near her - why do people wait??? I told her this would happen, but telling people doesn't make them listen does it?!
I'll keep updating and contact Nessa as well - thanks you guys!
