Jojo has been sneezing and wheezing a lot lately it hasn't been that bad till tonight. He's still very active and was even trying to explore outside of the cage but since my room isn't rat proofed yet I couldn't let him. I want to take him into the vet tomorrow but I don't know if I can and it's too late to call right now so I have to wait till morning. I've heard numerous time small doses of dark chocolate can help a bit. And I was just wondering about how much I should give him and cocoa %..
