My little guy eats so fast, from a speciality “squirrel nipple”, and now he has a clicking sounds when he breaths...just after this last feeding. He is 5 weeks old and weighs 122g. My local vet office is closed, but the feed store, which sells antibiotics for livestock, is still open. I’m wondering what I should get just to have on hand...just in case I need it. I have read hours of literature on proper care, and have had him for 2 weeks. He is being fed in the proper position, and all of that. I just need to know what to get and the dosing to give him. Any help is appreciated! Thank you!
