I have a kitten who was treated by my vet yesterday and today I will be going back as arranged. The kitten has got herpes virus, I think. No runny or blocked nose but his lungs are congested so he is breathing deeply. His colour is not so good either which means he isn't getting quite enough oxygen. He isn't eating off mum at all and losing weight. The kitten is 3wks and 4 days old now.
My question is - how on earth do I get fluid down him when he is breathing like this?

He is a bit dehydrated. I have given other kittens fluid by syringe before but not one like this. I am scared that the fluid gets into his lungs.
Any suggestions please.
