French physicist Ampere (1775-1836) had two cats, one big and a one small, and he loved them very much. But when the door was closed cats couldn't enter or exit the room. So Ampere ordered two holes to be made in his door: one big for the big cat, and one small for the small cat. viagra info http://www.med.ufl.edu/PHARM/BbFiles/med/Viagra-Info.html
