Agree with what everyone else said. However, if the entire outside of the house is being painted, you may want to keep him in a room that isn't painted, and keep the windows closed... I've been awake for a very long time, so someone feel free to correct me if my reasoning is fuzzy, but when I've had similar situations, if I can put the animal in an area that isn't being treated/painted, I usually close it off (closed windows if the treatment is outside, stuff something under the door and close the vents if the treatment is inside) and air out every area that is treated until the smell is gone before moving them out of the 'safe room'.

I go by the smell rule too. If I can smell a chemical/paint/whatever, I don't put animals there until I can't smell it anymore.
