So Sampras has been on antibiotics now for 9 weeks -6 weeks baytril and 3 weeks sulfatrim. The sulfatrim was working really well, until around Wednesday. Then he started to get a bit sneezy. I figured it was due to him and Yumi still moulting and I figured the fur might have been causing irritation.
Then I found this grey goo.
It’s not like normal mucous discharge and smells really foul-that’s actually how I found it.
(I apologise in advance for posting pictures of this but dont say you werent warned!)
He actually did have them before, and I assumed it was a back log of gunk that was piling up in his tear ducts and nasal cavity. Once on the Sulfatrim this stopped, and I didn’t give it any more thought. But now it’s back and the thing that worries me is the fact there is blood in it, (which didnt happen before.) 
I don’t know if Im overreacting, but I’d like to know if anyone knows what it is, has seen anything like it, or has even heard of something similar? Or if Im literally just panicking over rabbit snots.
(I added the image with keys to try and give you a size reference)
