The big rat kept sort of sneezing
I hope he is not sick :-(
Maybe it was really wheezing?
I'm not sure

Can you tell me if this is NORMAL in a White Rat?:D

I've had a rat Before so he might have something wrong with him Or Something in his cage could be Bothering him Like the stuff you cleaned the cage with I know it sounds crazy
But I washed out my Rats cage once and he Sneezed and Wheezed about it..
But you never know take him out of the cage into another part of the house or it could be a change to temperature If you moved the cage if he gets worce then Look Up different
Sites and if worce comes to worce take him to the vet
