So when i first got coffee i noticed he had an upper respiratory infection, well the start of one i should say, and my BFF is a ferret lover and had some Sulfadimethoxine in liquid from for birds that his vet gave him, and after a little math i figured out how much to give Coffee per day. I had read on here that they did not like the taste so i was trying to think of a way to get him to take it, i decided to see how he did with the seriange before i tried anything else, and what do you know he could not drink it fast enough he loved it. It had been 5 days now and he has stopped sneezing and his nose has cleared up really well, i just wanted to share this with other rat owners who may have an issue getting their babies to take their meds. I converted it to 5 ml per day. excuse the misspellings.
