About two weeks ago hurricane Laura came through Louisiana, and I rescued a little grey squirrel under the name of hammie. I have him on fox valley formula, the one you feed older squirrels as he’s over 5 weeks. He gets fed 4-5 hours in between. The past two days he’s been lethargic, barely opening his eyes, sneezing rapidly, although he has NO clicking. I also noticed he was regurgitating food, which cannot be a good sign. I’ve eased him off formula and started giving him small amounts with pedialyte. I have no clue has to why he’s had a dramatic drop in health. He weighs around 40g, which isn’t the best, but he was severely underfed when I picked him up! Please help, I do not want to lose my sweet boy!
