My cat Sophie had a litter of Kittens Feb 16th. They are 11 days old today. When she had them she had a little bit of a sneeze which has disappeared finally. But now two are sneezing and one of them has mucus around her eyes. I'm worried because they are not very old and I know there immune systems are not the best prepared for a sickness. So, Should I give it a few days and see if they get better or should I take them to the vet ASAP? This is the first litter of kittens I've taken care of and I just don't want them to die over something that could be fixed by me or a vet. Your advice will be HIGHLY appreciated!
