Much as expected we lost little Hector during the night

. Mouse is active and feeding this morning, having burped, pooed, wee'd and purred but, as we have found out with the others, that means nothing. Going to take him to the vet again this morning despite them all having seen one on Saturday. The vet did warn me last Tuesday that they'd probably not survive as we don't know what mum died of and we don't know if any of them got colostrum. Does anyone know if a week old kitten can be given antibiotics?
