I would watch him carefully for any sneezes, wispy breathing, runny nose, fever, watery eyes, or change in his poop.
Watch him carefully for any weight loss, or if he cuts back on the amount of his liquid or food intake. Any and all of these can often serve as an early warning to a future problem.
If
any of the above shows up, I would take him to the vet to be checked out. You could do this regardless, as a special caution, but that is up to you.
As an extra precaution I would;
(1) give him a child's chewable vitamin C daily
(2) papaya (dried or fresh or papaya enzyme sprinkled on his food)
(3) dried rose hips
(4) 1/2 and 1/2 Alfalfa and Timothy hay
This may sound a little extreme, but the extra vitamins in these items would not hurt him.
If it happens again ...
You can use a little (very little) baby shampoo and bathe him in a sink of luke warm water or room temperature water. Their skin is like a new born baby's skin and will easily burn ... the water should feel neither cold or warm to you.
Dry him first with a towel, then with paper towels (they absorb water faster and more efficiently).
A hair dryer can be used
with great caution after drying him as much as possible with paper towels.
The volume of air on the blow dryer should be on the lowest setting, the heat must be on the lowest setting.
Hold the dryer about 18 inches from the wet chin, constantly moving it back and forth. Taking short breaks to assure not over heating your chin. Make sure he is completely dry before putting him back in his cage.
So its to late now for me to clean him?
I would not do so now ... just give him extra dust baths.
