Thank you both. Someone said they look like rats which I guess to be fair they kind of do, and I found myself feeling really insulted.
Vet has checked Titch over and there's nothing obviously wrong with him so we just need to keep at the whole topping him up thing. Got a teat for the syringe which is helping a bit.
Interesting what you said about Meow. There's a little one I was worried about , she was only 64g when born but is doing fine now. Titch was bigger at 82g but lost a lot of weight the first day bless him. He was the last born.
Can't workout how to get pictures from phone to profile but here's a couple more:
Kitten scrumble
Titch
Pinot, I am Dorset/Hampshire border. Don't know how you did OT without the mother cat, I'm absolutely sodding knackered and have a stiff neck from spending my life on my knees, arse in air and head peering into a box!
