Heard some mewing earlier today and found a very cute kitten in the back garden. Noticed that our neighbours were also looking around outside in the front they could also hear mewing and had seen some kittens. I have now just noticed who I think is mum and we now have another two kittens in our back garden. The first kitten is now gone, we tried to catch it as we hadn't seen mum in a while and was worried about the cold weather. What should we do? Is mum trying to move the kittens? Should we just leave them be? I think they are ferral but I'm not 100% certain. Asked a couple of neighbours and cat doesnt belong to anyone nearby.
