I have a litter of siamese kittens that are very sick with an URI and I have them on clavamox as suggested by my vet.They are only 10 days old and now not eating at all.I have to force feed them with a bottle.I use my own recipe which works good.It's Karo syrup,water,evaporated milk,egg yolk.I wipe their eyes so they can open soon and they are very congested.One kitten is very tiny and very worried about her.They will not nurse.I feed them every 2 hours.The other 2 look like they are gaining weight.I don't know what else I can do.Any suggestions would be good.My vet isnt helping me much.
