Im taking care of five days old newborn kittens without their mom. (The mom is a stray cat and she is really sick in ICU; and I have zero experience with newborns). Ive been trying to bottle feed the kittens for past 10hrs with kitten formula with bottle that comes with the formula. I think something is wrong cause one of the kitten had sort of hiccups after the feeding and now there is this clicking sound in her chest and neck when she breathes. I did my best to feed them on their belly with their head elevated but they're really wiggly and angry. I am scared out of my mind that she's gotten the 'aspiration pneumonia' because of my shitty feeding skill and now there is formula in her lung!!!!!!!! I cant leave my place to go any vet because of corona lockdown at where I live. Its almost impossible to find open vet now at this time. (it's 3am in the morning here) I found one open vet and called them on the phone asking what I can do and he said "feed her! she must be hungry." I think this vet is an idiot. There is something wrong with this noise!! I am freaking out!!! what shall I do???!!!! PLEASE HELP!!!
