Hi, and thank you for all the advise!
This is what his poop looks like I did treat them again with permethrin dust and no more mites appeared so I’m guessing the first time got them all.
For worming medication And more specific dosages I’ll check tomorrow morning. I used both, Corid and Sulfa in slightly higher doses than suggested and I have discontinued them since.
Im baffled because the little guy acts totally normal. Eats, drinks, runs around, just doesn’t gain any weight (looks to like losing weight), so I’m guessing not absorbing much of what he eats... but still not fluffled up, not lethargic, doesn’t look sick otherwise ‍...
