i have started noticing my hamster sneezing lately and at first i have changed his bedding from chipsi-classic to tissues or toilet paper. But the new bedding started to stink alot and it was hard for me to clean . So what i did is that i washed the chipsi bedding and kept it out to dry its scent has reduced and my hamster doesnt sneeze much but now i have noticed it came back .
im not sure why he is sneezing? is it cause i dont clean his bedding often?
