URI and kittens

I have 6 foster kittens that are 8 weeks old and they all have URIs. All are very mild except for one that had a temp of 104.5 this morning and would not eat. I took him to the vet and they gave him some fluids and gave me eye drops and Clavomox for all of the kittens. I am free feeding them Eagle Pak kitten dry and giving them canned Royal Canin in the morning. The little guy that was so sick this morning did eat when he came home from the vets and his temp is down. Is there anything else I can do for these little guys. I have always fostered dogs so am less informed with the kittens. Any tips would be a great help.

Stopped up noses have a hard time smelling food and so they may not want to eat ... if you add a little warm water to the canned food to bring out the aroma, it might help. Also, congestion is relieved by humidity so if you can enclose babies in a room with a steam vaporizer that might also help to keep them from getting too stopped up.

Just as an aside, I don't care for Clavamox for kittens with a URI. It is my experience that Clavamox doesn't always address the specific bacteria and kittens may need to be on it longer - so I always request Baytril ... but ... a lot of vets are uncomfortable prescribing Baytril for kittens as it supposedly stunts growth. My way of thinking is that if a kitten isn't helped by the Clavamox and subsequently dies, that stunts growth too and it happens a lot faster than with giving Baytril. I just think giving the Baytril is the lesser of two evils.
