what i meant by bottom is did he have an anus - if everything looks to be in place then that probably means it is.

My comment about his cries is because of the risk of a cleft palate. Cleft palate kittens tend to not latch on, get neglected by mum (they sense something is wrong) and have a distinctive cry.

If he isnt feeding and youve got him warm properly, then i would get him to a vet asap today rather than tomorrow, and get the little fella checked over properly.

Remember its bank holiday too, so if you end up havng to see a vet tomorrow or monday its going to cost alot more.... not saying you wouldnt see a vet - just giving you a reminder of the bank holiday.
