Foster kitten didn't make

We're fostering another litter of kittens and just lost one last night It was very sudden and we got it to the vet as soon as we noticed but unfortunately he didnt make it. When we checked on him before he was playing and purring and eating, then an hour later he wasn't moving and was breathing slowly. He was the runt of the litter and very skinny and kind of boney. He would eat everytime we put food down, but it was hard to say how much because there are 4 others and they graze.

This is our second litter to foster so we are still very new to this. So wanted to know what kind of things to watch out or look for. It was just such a shock to us because he would play and eat, and then one minute later sick. This really devastated us and I've been wondering if there was anything we could have done or noticed early on to maybe prevent this. We just thought he was the runt

Forgot to add, but the vet thought it was either panleukapenia or where their body can't absorb the nutrients that it needs...forgot what they called that.

Also, we took the whole litter into the vet for a check up and they tested them all and no panleukapenia

I'm so sorry about losing the little one!    That is so sad!  I've read a lot of threads like this.  They say sometimes nothing will prevent one from dying sometimes.  They are just so fragile at that age.  If @catwoman707or @Kat0121  or @Margd  is here, one of them could advise you.  Hugs!
