i have a homemade cage in our bedroom for our 2 pet rats. they have been sneezing for over a month now but it seems to have slowed down since i started using aspen instead of the horse bedding pellets.

behind the cage, the wall has a bunch of red spots which looks like blood on the wall but im assuming its not blood? the female has red crusty stuff around her nose.

the male tried to breed her a week ago and was trying to breed her again last night so im guessing she didnt get pregnant the first time or could he just be frisky? im guessing her illness may be preventing her from conceiving?
