Tips to introduce guinea pigs?

First you can put there cage 10 feet from another so they can smell each other at a safe distance. Never put them next to each other or into each other's cage yet because they will get territorial and fight. The best option is to put them in a neutral place like a bathtub and let them get to know each other. If they fight, use gloves and break them up and put them away until the next dy. Keep putting them together until they have no problem with each other. Than completely clean out the cage you are going to have both of them in with diluted bleach so the scent of the guinea pig isn't there. Put them together and see what happens. There may be a little tussling to establish order but no blood no foul. Just make sure they are bother getting food and water and you should have two happy healthy piggies.
