Muffin always has a tiny bit of wetness on her nose, but never sounds congested. Hope the vet goes well--you usually don't need to bring poos especially since he doesn't have GI complaints. Some vets want to do a fecal yearly but it's probably not needed. I would definitely put hay in with him and attach a water bottle to the side if you have one and he'll drink from it. A bowl would be a disaster. Bring any and all papers you have on him, from the shelter, breeder, previous owner, etc. Write down what you feed him and his litter type/brand unless you can remember it.
