My rat has a bloody nose!
Although it looks like blood, don’t worry–it’s just tears. It’s called porphyrin. Rats have a large glad behind their eyes that produce it, and because the eyes are connected to the nose, you’ll often find it caked around their eyes and nose. Many first-time rat owners see this are concerned that their rat has a bloody nose.
Why does it happen? Porphyrin may show up when a rat is stressed, but it’s also a sign of a respiratory infection. You might want to get your rat checked out by a vet, especially if she’s sneezing or showing any other signs of a respiratory infection.
For more scientific information about porphyrin, check out the links page under “health problems.”

i have onlt had my little 5 month old rat, willow, for 3 days and she has been sneezing all the time i’ve had her. Once when she sneezed there was a little blood spekkle on her bedding! OH NO! she is the first rat any of my family has owned, so none of us know what to expect. Should i take her to the vet?
