The only thing that might give them real trouble is floor paint - that has really nasty fumes.
Water based gloss paint isn't as good a finish as solvent based, but no fumes. Normal wall paint has fumes that won't interfere. Even the rather stronger kitchen/bathroom wall paint is non fume.
Solvent based gloss paint will only cause a problem if you have asthmatic piggies. Once the paint is starting to go on, pick your piggies up and listen to their breathing by putting your ear to their side. It is a good idea to do this tonight so that you know what breathing easy should sound like - and can tell the breathing apart from the teeth grinding, tummy rumbling and general excited squeebling (I'm on your shoulder! I'm on your shoulder!)
If there is a problem, the worst of the fumes will be gone in the time it takes to touch dry - it will say on the tin. I think this is about two hours for gloss. During this time the window in the room being painted must be open anyhow. You may wish to open the window in the piggies room for this time and give them somewhere warm to huddle.
Any piggie that shows real difficulty breathing from the fumes will need to be taken to a far away room - a box or washing basket will do, and allowed to breathe clean air.
I doubt very much your piggies will be affected, only if there are genuine underlying breathing problems. But it is as well to be sure and do please check their breathing.
I know about all this through being a chemist and a school teacher - sorry if this comes across as a bit 'lecturing'! All the best, Sarah
PS If there any piggy owners on here who have not yet listened to their piggies sides to hear good breathing and what a happy tummy should sound like then please do. You will have a good reference in case of problems later on then! And it's fun!
