Thank you for your advice.
Unfortunately we lost one of the kittens today. It was the smallest of the litter and I think it just wasn't strong enough to fight for the milk - I had no idea they fight the way they do already. Survival of the fittest I guess. Anyway I noticed it was tiny so took Sarah aside and brought the tiny one to her to feed on its own and it just wouldn't, it was almost as if it didn't know what to do. I put its mouth next to the nipple and it just tried to climb up Sarah's body. In the basket it was crawling away from her, meowing loudly. I went to the pet shop and bought a kitten feeding kit, but when I got home it was almost dead.
It took a few gasps but its chest was not moving. I worked on it a while but I could only get it to gasp every few mins so I just gave it back to Sarah and she licked it etc but when I got home from picking my son up from school, the kitten is stiff.
How could it be fighting for life - meowing, crawling around etc then 2 hours later be gasping its last breaths? I am so upset I can't believe it - I have no idea how I got so attached to it after just 2 days.
Poor little thing - it was the one I was considering keeping too cos it was just so cute and so sweet. I keep thinking if only I had tried to feed it earlier then it would be ok.
I am finding it hard to come to terms with burrying it in the garden - "just in case" - but if it is stiff then it is definitely dead, right?
