My 5 month old Fox squirrel that I have been rehabbing started sneezing yesterday and is wobbly and weak. His sister is fine and bouncing off the walls. He has had a sneezing episode before where he knocked a bunch of cardboard mulch onto his face and then was fine the next day. He is still eating and drinking and is on the required rodent block for nutritional reasons but I had to get a different kind this time and took a good day for them to eat it. He has almonds, spinach, grapes, blueberries, walnuts,and apples as snacks throughout the day. He has always been super active and really silly so hard to see him like this. The sneezing seems to be when he is sitting still or lying down but it stops long enough to eat etc.
