Get the rest of your pets out of there immediately!  It sounds like you
have either carbon monoxide or radon in the house.  Get a detector for
both and have it checked.  Do you use an exterminator?  Could there be
something he is spraying.  Has the vet checked for signs of poison?  Call
the poison control center and speak to them about this.  They may have
some ideas.  If it affects others when they are there but goes away when
they are gone then you can bet its something in the air.  Dizziness, light
headedness, aches and pains can be from carbon monoxide or natural gas
leaks.  I'd call your local housing authority and ask them to recommend
experts that can come and check the house out.
